PRODUCTION DATA
The DRV8317 integrates three high-performance low-side current sense amplifiers for current measurements using built-in current sense. Low-side current measurements are commonly used to implement overcurrent protection, external torque control, or brushless DC commutation with the external controller. Each amplifier senses the current in the corresponding half-bridge when the low-side MOSFET is conducting. The current sense amplifiers include features such as configurable gain (through CSA_GAIN register or GAIN pin) and an external voltage reference (VREF) provided through CSAREF pin.
