The DRV8316C integrates three, high-performance low-side current sense amplifiers for current measurements using built-in current sensing. Low-side current measurements are commonly used to implement overcurrent protection, external torque control, or brushless-DC commutation with an external controller. The three amplifiers can be used to sense the current in each of the half-bridge legs (when the low-side FET of the corresponding phase is conducting current). The current sense amplifiers include features such as programmable gain and external reference (which is provided on the voltage reference pin, VREF).
