Application Information
- Driver Control The mute function of the driver can be used by switching the MUTE and CNT terminals to High and Low levels. The table below shows the logic. INPUT OUTPUT MUTE CNT CH1,3,4 CH2 H H ACTIVE LD ON H L ACTIVE SL ON L H MUTE LD ON L L MUTE MUTE SL : SLED LD : LOADING 2. BIAS Drop Mute If BIAS terminal (Pin 20) voltage becomes 0.7V (Typ) or less, output of all channels turns OFF. Please set it to a minimum of 1.3V for typical use. (However, the mute function doesn't work for CH2 when CNT=High. ) 3. PREVCC Drop Mute If PREVCC terminal voltage becomes 3.8V (Typ) or less, output of all channels turns OFF. If PREVCC terminal voltage becomes 4.0V (Typ) or more, output of all channels turns ON. 4. Thermal shutdown circuit (TSD) Thermal shutdown circuit is designed to turn off output of all channels when the junction temperature (Tj) reaches 175°C (Typ) (with 25°C (Typ) hysteresis). 5. Regulator Output voltage of the regulator (VREGOUT) is set according to the following expression. R2 R1VV REGPREGOUT Please disable the oscillation prevent ion beforehand, and use the capacitor connected between the regulator output (VREGOUT) and PREGND after confirming parameters such as temperature characteristics in actual operation. The power supply voltage fluctuation described in the Electrical Characteristics is obtained when VREGOUT is 5V. Please note that fluctuation bands increase from the described values if VREGOUT is set to a value bigger than 5V.

Reverse Connection of Power Supply Connecting the power supply in reverse polarity can damage the IC. Take precautions against reverse polarity when connecting the power supply, such as mounting an external diode between the power supply and the IC’s power supply terminals. 2. Power Supply Lines Design the PCB layout pattern to provide low impedanc e ground and supply lines. Separate the ground and supply lines of the digital and analog blocks to prevent noise in the ground and supply lines of the digital block from affecting the analog block. Furthermore, connect a capacitor to gr ound at all power supply pins. Consider the effect of temperature and aging on the capacitance value when using electrolytic capacitors. 3. Ground Voltage Ensure that no pins are at a voltage below that of the ground pin at any time, even during transient condition. However, pins that drive inductive loads (e.g. motor driver outputs, DC-DC converte r outputs) may inevitably go below ground due to back EMF or electromotive force. In such cases, the user should make sure that such voltages going below ground will not cause the IC and the system to malfunction by exam ining carefully all relevant factors and conditions such as motor characteristics, supply voltage, operating frequency and PCB wiring to name a few. 4. Ground Wiring Pattern When using both small-signal and large-current ground traces, the two ground traces should be routed separately but connected to a single ground at the refe rence point of the application board to avoid fluctuations in the small-signal ground caused by large currents. Also ensure that the ground traces of external components do not cause variations on the ground voltage. The power supply and ground lines must be as short and thick as possible to reduce line impedance. 5. Thermal Consideration Should by any chance the power dissipation rating be exceed ed the rise in temperature of the chip may result in deterioration of the properties of the ch ip. The absolute maximum rating of the Pd stated in this specification is when the IC is mounted on a 70mm x 70mm x 1.6mm glass epox y board. In case of exceeding this absolute maximum rating, increase the board size and copper area to prevent exceeding the Pd rating. 6. Recommended Operating Conditions These conditions represent a range within which the ex pected characteristics of the IC can be approximately obtained. The electrical characteristics are guaranteed under the conditions of each parameter. 7. Rush Current When power is first supplied to the IC, it is possible that the internal logic may be unstable and inrush current may flow instantaneously due to the internal powering sequence and delays, especially if the IC has more than one power supply. Therefore, give special consi deration to power coupling capacitance, power wiring, width of ground wiring, and routing of connections. 8. Operation Under Strong Electromagnetic Field Operating the IC in the presence of a strong electromagnetic field may cause the IC to malfunction. 9. Testing on Application Boards When testing the IC on an application board, connecting a capacitor directly to a low-impedance output pin may subject the IC to stress. Always dischar ge capacitors completely after each process or step. The IC’s power supply should always be turned off completely before connecting or removing it from the test setup during the inspection process. To prevent damage from static discharge, ground the IC during assembly and use similar precautions during transport and storage. 10. Inter-pin Short and Mounting Errors Ensure that the direction and position are correct when mounting the IC on the PCB. Incorrect mounting may result in damaging the IC. Avoid nearby pins being shorted to each other especially to ground. Inter-pin shorts could be due to many reasons such as metal particles, water droplets (i n very humid environment) and unintentional solder bridge deposited in between pins during assembly to name a few.
