3 Description

The DRV8000-Q1 device integrates multiple types of

drivers intended for multiple functions: driving and

diagnosing motor (inductive), resistive and capacitive

loads. The device features two half-bridge gate

drivers, 6 integrated half-bridges, 6 integrated highside

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. Each

individual driver has PWM input control options,

sensing and diagnostics, along with device system

protection and diagnostics. There are also dedicated

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.

The high-side and low-side drivers can be used to

drive MOSFETs for special loads such as heating

element or electro-chromic elements. These drivers

include offline and active diagnostics.

The device provides protection features such as

under and over voltage monitors, offline open load

and short circuit diagnostics, and zone-based thermal

monitoring and shutdown protection.
