3 Description
The UCC5304 device is an isolated single-channel gate driver with 4-A peak-source and 6-A peak-sink current. It is designed to drive power MOSFETs and GaNFETs in PFC, Isolated AC/DC, DC/DC, and synchronous rectification applications, with fast switching performance and robust ground bounce protection through greater than 100-V/ns common- mode transient immunity (CMTI). The UCC5304 is available in a 8.5 mm SOIC-8 (DWV) package and can support isolation voltage up to 5-kVRMS. Compared to an optocoupler, the UCC5304 family has lower part-to-part skew, lower propagation delay, higher operating temperature, and higher CMTI. Protection features include: IN pin rejects input transient shorter than 5-ns; both input and output can withstand –2-V spikes for 200-ns, both supplies have undervoltage lockout (UVLO), and active pull down protection clamps the output below 2.1-V when unpowered or floated. With these features, this device enables high efficiency, high power density, and robustness in a wide variety of power applications.

6.7 Safety-Related Certifications
Plan to certify according to DIN V VDE V 0884-11:2017-01 Plan to be recognized under UL 1577 Component Recognition Program Plan to certify according to GB 4943.1-2011 (1) The maximum safety temperature, TS, has the same value as the maximum junction temperature, TJ, specified for the device. The IS and PS parameters represent the safety current and safety power respectively. The maximum limits of IS and PS should not be exceeded. These limits vary with the ambient temperature, TA. The junction-to-air thermal resistance, RθJA, in the Thermal Information table is that of a device installed on a high-K test board for leaded surface-mount packages. Use these equations to calculate the value for each parameter: TJ = TA + RθJA × P, where P is the power dissipated in the device. TJ(max) = TS = TA + RθJA × PS, where TJ(max) is the maximum allowed junction temperature. PS = IS × VI, where VI is the maximum input voltage.

8 Detailed Description
8.1 Overview
In order to switch power transistors rapidly and reduce switching power losses, high-current gate drivers are often placed between the output of control devices and the gates of power transistors. There are several instances where controllers are not capable of delivering sufficient current to drive the gates of power transistors. This is especially the case with digital controllers, since the input signal from the digital controller is often a 3.3-V logic signal capable of only delivering a few mA. The UCC5304 is a flexible gate driver that can be configured to fit a variety of power supply and motor drive topologies, as well as drive several types of transistors. UCC5304 has many features that allow it to integrate well with control circuitry and protect the gates it drives such as under voltage lock-out (UVLO) for both input and output voltages. The UCC5304 holds its output low when the input is left open or when the input pulse is not wide enough. The driver input pin is CMOS and TTL compatible for interfacing with digital and analog power controllers alike.

non-ideal layout or long PCB traces. example, an RIN = 51 Ω and a CIN = 33 pF are selected, with a corner frequency of approximately 100 MHz.
9.2.2.2 Estimating Junction Temperature
- TC is the UCC5304 case-top temperature measured with a thermocouple or some other instrument, ψJT is the junction-to-top characterization parameter from the Thermal Information table. Importantly, ψJT is developed based on JEDEC standard PCB board and it is subject to change when the PCB board layout is different. For more information, please visit application report - semiconductor and IC package thermal metrics. (1) Using the junction-to-top characterization parameter (ΨJT) instead of the junction-to-case thermal resistance (RΘJC) can greatly improve the accuracy of the junction temperature estimation. The majority of the thermal energy of most ICs is released into the PCB through the package leads, whereas only a small percentage of the total energy is released through the top of the case (where thermocouple measurements are usually conducted). RΘJC can only be used effectively when most of the thermal energy is released through the case, such as with metal packages or when a heatsink is applied to an IC package. In all other cases, use of RΘJC will inaccurately estimate the true junction temperature. ΨJT is experimentally derived by assuming that the amount of energy leaving through the top of the IC will be similar in both the testing environment and the application environment. As long as the recommended layout guidelines are observed, junction temperature estimates can be made accurately to within a few degrees Celsius. For more information, see the Layout Guidelines and Semiconductor and IC Package Thermal Metrics application report.

9.2.2.3.1 Selecting a VCCI Capacitor
A bypass capacitor connected to VCCI supports the transient current needed for the primary logic and the total current consumption, which is only a few mA. Therefore, a 25-V MLCC with over 100 nF is recommended for this application. If the bias power supply output is a relatively long distance from the VCCI pin, a tantalum or electrolytic capacitor, with a value over 1 µF, should be placed in parallel with the MLCC.
9.2.2.3.2 Selecting a VDD Capacitor
A 50-V, 10-µF MLCC and a 50-V, 220-nF MLCC are chosen for CVDD. If the bias power supply output is a relatively long distance from the VDD pin, a tantalum or electrolytic capacitor with a value over 10 µF, should be used in parallel with CVDD.

10 Power Supply Recommendations
The recommended input supply voltage (VCCI) for UCC5304 is between 3 V and 5.5 V. The output bias supply voltage (VDD) range from 9.2V to 18V. The lower end of this bias supply range is governed by the internal under voltage lockout (UVLO) protection feature of each device. One mustn’t let VDD or VCCI fall below their respective UVLO thresholds (For more information on UVLO see VDD, VCCI, and Under Voltage Lock Out (UVLO)). The upper end of the VDD range depends on the maximum gate voltage of the power device being driven by UCC5304. The UCC5304 has a recommended maximum VDD of 18 V. A local bypass capacitor should be placed between the VDD and VSS pins. This capacitor should be positioned as close to the device as possible. A low ESR, ceramic surface mount capacitor is recommended. It is further suggested that one place two such capacitors: one with a value of ≈10-µF for device biasing, and an additional ≤100-nF capacitor in parallel for high frequency filtering.. Similarly, a bypass capacitor should also be placed between the VCCI and GND pins. Given the small amount of current drawn by the logic circuitry within the input side of UCC5304, this bypass capacitor has a minimum recommended value of 100 nF.

11 Layout
11.1 Layout Guidelines
Consider these PCB layout guidelines for in order to achieve optimum performance for the UCC5304.
11.1.1 Component Placement Considerations
- Low-ESR and low-ESL capacitors must be connected close to the device between the VCCI and GND pins and between the VDD and VSS pins to support high peak currents when turning on the external power transistor.
- To avoid large negative transients on the switch node VSS pin in a half-bridge application, the parasitic inductances between the source of the top transistor and the source of the bottom transistor must be minimized.
11.1.2 Grounding Considerations
- It is essential to confine the high peak currents that charge and discharge the transistor gates to a minimal physical area. This will decrease the loop inductance and minimize noise on the gate terminals of the transistors. The gate driver must be placed as close as possible to the transistors.
11.1.3 High-Voltage Considerations
- To ensure isolation performance between the primary and secondary side, one should avoid placing any PCB traces or copper below the driver device. A PCB cutout is recommended in order to prevent contamination that may compromise the UCC5304 isolation performance.
- For half-bridge, or high-side/low-side configurations, one should try to increase the clearance distance of the PCB layout between the high and low-side PCB traces.
11.1.4 Thermal Considerations
- A large amount of power may be dissipated by the UCC5304 if the driving voltage is high, the load is heavy, or the switching frequency is high (Refer to for more details). Proper PCB layout can help dissipate heat from the device to the PCB and minimize junction to board thermal impedance (θJB).
- Increasing the PCB copper connecting to VDD and VSS pins is recommended, with priority on maximizing the connection to VSS (See and ). However, high voltage PCB considerations mentioned above must be maintained.
- If there are multiple layers in the system, it is also recommended to connect the VDD and VSS pins to internal ground or power planes through multiple vias of adequate size. Ensure that no traces or coppers from different high-voltage planes overlap.

Device is in production to support existing customers, but TI does not recommend using this part in a new design. PREVIEW: Device has been announced but is not in production. Samples may or may not be available. OBSOLETE: TI has discontinued the production of the device. (2) RoHS: TI defines "RoHS" to mean semiconductor products that are compliant with the current EU RoHS requirements for all 10 RoHS substances, including the requirement that RoHS substance do not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, "RoHS" products are suitable for use in specified lead-free processes. TI may reference these types of products as "Pb-Free". RoHS Exempt: TI defines "RoHS Exempt" to mean products that contain lead but are compliant with EU RoHS pursuant to a specific EU RoHS exemption. Green: TI defines "Green" to mean the content of Chlorine (Cl) and Bromine (Br) based flame retardants meet JS709B low halogen requirements of <=1000ppm threshold. Antimony trioxide based flame retardants must also meet the <=1000ppm threshold requirement. (3) MSL, Peak Temp. - The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature. (4) There may be additional marking, which relates to the logo, the lot trace code information, or the environmental category on the device. (5) Multiple Device Markings will be inside parentheses. Only one Device Marking contained in parentheses and separated by a "~" will appear on a device. If a line is indented then it is a continuation of the previous line and the two combined represent the entire Device Marking for that device. (6) Lead/Ball Finish - Orderable Devices may have multiple material finish options. Finish options are separated by a vertical ruled line. Lead/Ball Finish values may wrap to two lines if the finish value exceeds the maximum column width.
