The DRV8316 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. All three amplifiers can be used to sense the current in each of the half-bridge legs (low-side FETs). The current sense amplifiers include features such as programmable gain and external reference is provided on a voltage reference pin (VREF).
