A89503

80 V Automotive Half-Bridge MOSFET Driver

FEATURES AND BENEFITS

DESCRIPTION

TheA89503isanN-channelpowerMOSFETdrivercapableof

controllingMOSFETsconnectedinahalf-bridgearrangement

and is specifically designed for automotive applications with

high-power inductive loads, such as brush DC motors, BLDC

motors, VR/SR motors, solenoids, and actuators.

• Half-bridge MOSFET driver

• Bootstrap gate drive for N-channel MOSFET bridge

• Independent control of high-side and low-side gate drives

with cross-conduction capability

• Charge pump regulator for low supply voltage operation

• 5.5 to 80 V supply voltage operating range

• Integrated logic I/O supply

• SPI-compatible serial interface

• Bridge control by direct logic inputs or serial interface

• Programmable gate drive

fullsupplyvoltagerangefrom5.5to80Vformostapplications.

A bootstrap capacitor is used to provide the above-battery

supply voltage required for N-channel MOSFETs.

EachMOSFETcanbe independentlycontrolledbylogic-level

inputs or through the SPI-compatible serial interface. Fully

independent control allows both external FETs to be turned

on at the same time.

• Current sense amplifier

• Programmable diagnostics

• A²SIL™ product—device features for

safety-critical systems

Integrated diagnostics provide indication of multiple internal

faults, system faults, and power bridge faults, and can be

configured to protect the power MOSFETs under most short

circuit conditions.

In addition to providing full access to the bridge control, the

serialinterfaceisalsousedtoalterprogrammablesettingssuch

as VDS threshold and fault blank time. Detailed diagnostic

information can be read through the serial interface.

PACKAGE:

24-lead TSSOP with

exposed pad (suffix LP)

TheA89503wasdevelopedinaccordancewithISO26262:2011

asahardwaresafetyelementoutofcontextwithASILBcapability

(pending assessment) for use in automotive safety-related

systems when integrated and used in the manner prescribed in

the applicable safety application note and datasheet.

The A89503 is supplied in a 24-lead eTSSOP (suffix LP).

This package is lead (Pb) free, with 100% matte-tin leadframe

plating (suffix –T).
