Description for the DRV8316

The DRV8316 provides three half-H-bridge integrated MOSFET drivers for driving a three-phase Brushless-DC (BLDC) motor for 12-V/24-V DC rails or battery powered applications. These applications include field-oriented control (FOC), sinusoidal current control, and trapezoidal current control of BLDC motors. The device integrates three current-sense amplifiers (CSA) with built-in current sense for sensing the three phase currents of BLDC motors.

Each output driver channel consists of N-channel power MOSFETs configured in a half-bridge configuration. Various PWM control modes are supported for simple interfacing to control circuits that can be powered by the 30-mA, 3.3-V internal regulator (AVDD). The DRV8316R/T also supports a buck regulator which in conjunction can support 200-mA with programmable regulated supply. The device supports 200-kHz maximum PWM frequency.

Internal protection functions are provided for undervoltage lockout (UVLO), Overvoltage protection (OVP), charge pump undervoltage (CPUV), overcurrent protection (OCP), over-temperature warning (OTW) and over-temperature shutdown (OTSD). Fault conditions are indicated by the nFAULT pin.
