3 Description

The DRV8000-Q1 device integrates multiple door

control specific functions: driving and diagnosing

motor (inductive), resistive and capacitive loads,

driving a lamp or LEDs, drive MOSFETs for special

loads such as heating element or electrochromic

elements. 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 zone-based thermal

monitoring and shutdown protection. The device

features two half-bridge gate drivers, 6 integrated halfbridges

(2 high-side alternate modes), 6 integrated

high-side drivers, one external high-side gate driver

for heater, one external high-side gate driver for

electrochromic charge and one integrated low-side

driver for electrochromic load discharge. The halfbridge,

high-side, heater and gate 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.
