3 Description
The DRV871x-Q1 family of devices are highly
integrated, multi-channel gate drivers intended for
driving multiple motors or loads. The devices integrate
either 4 (DRV8714-Q1) or 8 (DRV8718-Q1) halfbridge
gate drivers, driver power supplies, current
shunt amplifiers, and protection monitors reducing
total system complexity, size, and cost.
A smart gate drive architecture manages dead time to
prevent shoot-through, controls slew rate to decrease
electromagnetic interference (EMI), and optimizes
propagation delay for optimal performance.
Input modes are provided for independent halfbridge
or H-bridge control. Four PWM inputs can
be multiplexed between the different drivers in
combination with SPI control.
Wide common mode shunt amplifiers provide inline
current sensing to continuously measure motor
current even during recirculating windows. The
amplifier can be used in low-side or high-side sense
configurations if inline sensing is not required.
The devices provide an array of protection features to
ensure robust system operation. These include under
and overvoltage monitors, VDS overcurrent and VGS
gate fault monitors for the external MOSFETs, offline
open load and short circuit diagnostics, and internal
thermal warning and shutdown protection.
