Semiconductor Technical Data MOTOROLA Order Number: MC33286/D Rev. 5.4, 06/2001 This document contains information on a new product. Specifications and information herein are subject to change without notice. © Motorola, Inc., 2001. All rights reserved. TM This device is a dual high side power switch dedicated for automoive applications. In comparison with mechanical relays, this device offers higher reliability as well as protection and diagnostic features. The device consists of two independent 35m Ω Rdson switches in a surface mount package. It can be directly interfaced with a microcontroller for control and diagnostic functions. The device is fully protected against overcurrents, short-circuits and incorporates an overtemperature shutdown. It can be directly and continuously supplied by the battery and offers a very low quiescent current in standby mode. Designed for Automotive Applications Junction T emperature Range from -40°C to 150°C Operating Voltage Range from 8V to 40V Maximum Breakdown Voltage greater than 40V Surface Mount Package 35mΩ Rdson at 25°C Overtemperature Protection with Hysteresis Under Voltage Shutdown Reverse Battery protected Open Load Detection in On-State Diagnostic Output ESD Protection 2kV Current Limitation at 30A Loss of ground protected Standby Current less than 10 µA at Vbat = 14V Freescale Sem iconductor, I Freescale Semiconductor, Inc.

Automotive Dual High Side Driver 4 Pin No. Name/Function Description 1, 2, 5, 6, 15, 16, 19, 20 V bat Supply Voltage These are the power supply pins of the device. These pins are directly connected with the lead frame of the package and are tied to the drain of the switching MOSFET. These pins can be directly connected to the battery voltage. In addition to their supply functions, these pins participate to the thermal behaviour of the device in conducting the heat from the switching MOSFET to the printed circuit board. 3, 4, 18, 17 OUT1 OUTPUT Channel 1 OUT 2 OUTPUT Channel 2 Pins 3 and 4 are the output 1 terminals. Pins 17 and 18 are the output 2 terminals. They are directly connected to the source of the power MOSFET. The Rdson is 35m Ω max per output at 25 °C. Its value increases up to 50mΩ at 150°C junction temperature. 8, 13 IN 1 INPUT Channel 1 IN 2 INPUT Channel 2 These are the device input pins, which directly control their associated output. The thresholds are CMOS compatible. When the input is in low state, the associated output MOSFET is off. When input is high, the MOSFET is turned on and the load is activated. When both inputs are low, the device is in standby mode and its supply current is less than 1mA for V bat up to 12V. 9, 12 St1 Status for Channel 1 St2 Status for Channel 2 These pins are the channel 1 and 2 status. Their internal structure is an open drain with an internal clamp at 6V. An external pull up connected to the 5V is needed. When the device is in normal condition the status is high. If open load or overtemperature occurs on one channel, the associated output status will be pulled low. See Functional Truth T able.
10 V batc
This pin is the supply voltage pin for the control portion of the device. It has to be connected to the Vbat line and to the other Vbat pins listed above. An internal 45V zener diode is connected between pin 10 and Gnd.
11 GND
This is the Gnd pin of the device. Freescale Sem iconductor, I Freescale Semiconductor, Inc. For More Information On This Product, Go to: www.freescale.com nc...
Automotive Dual High Side Driver 6 comparator has an hysteresis which maintains the device off. As soon as the die power temperature decreases by around 20°C the device automatically switches on again. If the cause of the overtemperature has not been removed, it is likely that the device will reach the overtemperature shutdown again and will cycle off and on until the overtemperature cause is removed. As soon as the device switches off, due to overtemperature, the status pin is pulled low to inform the microcontroller that an abnormal condition has occured.
