Semiconductor Technical Data Advance Information Dual High Side Switch for H-Bridge Automotive Applications This device is a dual high side switch for automotive applications which incorporates a dual low side switch control feature. This device is designed to monitor two low side switches for typical DC-motor control in an H-Bridge configuration. It can be directly interfaced with a microcontroller for control and diagnostic functions, is PWM capable and has a self-adjusted switching speed for minimizing electromagnetic emission. The High Side block incorporates two Rdson N-Channel power Mosfets with senses and a control circuitry. Each output of this high side block is protected against short to gnd and load shorts, and has over temperature detection with hysteresis. It includes a current recopy feature for monitoring the load current. The control circuitry also has an overvoltage detector which turns off the bridge and protects the load in case of Vbat exceeding 28V. The low side control block is able to drive 2 low sides switches in a H-bridge configuration and protects them in case of short circuit. This, in combination with the High side protection, fully protects the H-bridge from shorted loads, shorts to Vbat and shorts to GND. This device offers a very low quiescent current in standby mode. •10 Amps Nominal DC Current •35 Amps Maximum Peak Current •DC Voltage from -0.3V to 40V •Operating Voltage from 8 to 28V •Overvoltage Detection Switch Off when Vbat Exceed 28V •High Side and Low Side Overcurrent protection •Operating Junction Temperature - 40°C to 150°C •Rdson max at 25C° per Mosfet •DC to 30kHz PWM Capability •Standby Mode with Low Standby Current •Junction to Case Thermal Resistance 2°C/W •ESD protection 2kV •Current Recopy to Monitor the High-Side Current •Common diagnostic output MC33486 DUAL HIGH SIDE SWITCH FOR H-BRIDGE AUTOMO- TIVE APPLICATIONS SEMICONDUCTOR TECHNICAL DATA DH SUFFIX HSOP20 Package CASE 979-04 D2PAK D2PAK PIN ASSIGNMENT Gnd 1 Cur R 2 IN1 3 GLS1 4 OUT1 5 OUT1 6 OUT1 7 OUT1 8 NC 9 NC 10 Vbat 21 21 Vbat 20 Wake 19 St 18 IN2 17 GLS2 16 OUT2 15 OUT2 14 OUT2 13 OUT2 12 NC 11 NC Simplified Block Diagram and Typical Application High Side Block St IN1 IN2 WAKE Cur R Control GLS1 OUT1 VBAT GLS2 OUT2 Low Side Block This document contains information on a new product.

Dual High Side Switch for H-Bridge Automotive Applications

This device is a dual high side switch for automotive applications which incorporates a dual low side switch control feature. This device is designed to monitor two low side switches for typical DC-motor control in an H-Bridge configuration. It can be directly interfaced with a microcontroller for control and diagnostic functions, is PWM capable and has a self-adjusted switching speed for minimizing electromagnetic emission.

The High Side block incorporates two Rdson N-Channel power Mosfets with senses and a control circuitry. Each output of this high side block is protected against short to gnd and load shorts, and has over temperature detection with hysteresis. It includes a current recopy feature for monitoring the load current. The control circuitry also has an overvoltage detector which turns off the bridge and protects the load in case of Vbat exceeding 28V.

The low side control block is able to drive 2 low sides switches in a H-bridge configuration and protects them in case of short circuit. This, in combination with the High side protection, fully protects the H-bridge from shorted loads, shorts to Vbat and shorts to GND.

This device offers a very low quiescent current in standby mode.
