The DRV8000-Q1 device integrates multiple types of drivers intended for multiple functions: driving and diagnosing motor (inductive), resistive and capacitive loads. The devices features two half-bridge gate drivers, 6 integrated half-bridges, 6 integrated high-side drivers, one high-side external MOSFET gate driver for heater, one high-side gate driver for electrochromic charge and one integrated low-side driver for electrochromic load discharge. Each driver features current sensing, protection and diagnostics along with system protection and diagnostics, which increases system integration and reduces total system size and cost.

The device half-bridge external MOSFET gate driver architecture automatically manages dead time to prevent shoot-through, controls slew rate to decrease electromagnetic interference (EMI), and configurable propagation delay for optimized performance. These gate drivers support input modes for independent half-bridge or H-bridge control. Two PWM inputs can be configured as polarity and drive control. The external MOSFET gate driver protection circuits include charge pump monitoring, short circuit protection (V_DS fault monitoring) and open load detection (V_GS fault monitoring).

The half-bridge drivers can be controlled through SPI register or PWM pins PWM1 and IPROPI/PWM2. The half-bridges have configurable current chopping scheme called ITRIP. Protection cricuits include short circuit protection, active and passive open load detection.

The high-side drivers can be controlled through SPI register, external PWM pin (PWM1), or with a dedicated PWM generator which enables load regulation during operation. High-side drivers also have optional constant current mode regulation for LED module loads. One high-side driver is configurable to drive either a lamp or LED load. Protection circuits include short circuit protection and open load detection.

The device also has an external MOSFET drivers for resistive heating element. The heater MOSFET driver can be controlled with SPI register or with PWM pin (PWM1) and feature both short circuit and open load detetction.

There is also an electrochromic (EC) mirror driver. The EC driver is controlled only through SPI register. For EC drive, the driver control loop regulates the EC voltage to a 6-bit target voltage. To discharge the EC element or change target voltage, there is an integrated low-side MOSFET to discharge the EC element in either two discharge modes, a PWM discharge and fast discharge options. The EC driver protection includes LS overcurrent and open load detection.

IPROPI (IPROPI/PWM2) pin is a multi-purpose output pin or input PWM pin (PWM) that can provide proportional current sense from any integrated driver with current sense. IPROPI can be also configured to output a scaled down PVDD input voltage, internal temperature cluster output voltage, or can be configured as a second PWM input option for half-bridges.
