3 Description

The DRV8002-Q1 device integrates multiple door

control specific functions: driving and diagnosing

motor (inductive), resistive and capacitive loads,

driving a lamp or LEDs. These drivers include

protection features for offline and active diagnostics

such as under and over voltage monitors, offline

open load and short-circuit diagnostics, and zonebased

thermal monitoring and shutdown protection.

The device features two half-bridge gate drivers,

6 integrated half-bridges (2 high-side alternate

modes) and 6 integrated high-side drivers. The

half-bridgeand high-side drivers have PWM input

control configuration, sensing, diagnostics and device

system protection. There is a dedicated internal

programmable PWM generators for each high-side

driver. Proportional current sense pin output is

available for all integrated drivers, along with a robust

and flexible current shunt amplifier for the gate driver.
