DRV8313 www.ti.com SLVSBA5A – OCTOBER 2012 – REVISED NOVEMBER 2012 FUNCTIONAL DESCRIPTION Output Stage The DRV8313 contains three half-H-bridge drivers. The source terminals of the low-side FETs of all three half-Hbridges terminate at separate pins (GND1, GND2, and GND3) to allow the use of a low-side current-sense resistor on each output, if desired.

DRV8313 SLVSBA5A – OCTOBER 2012 – REVISED NOVEMBER 2012 www.ti.com Comparator The DRV8313 includes an uncommitted comparator, which can find use as a current-limit comparator or for other purposes. The following diagram shows connections to use the comparator to sense current for implementing a current limit. Current from all three low-side FETs is sensed using a single low-side sense resistor.

DRV8313 www.ti.com SLVSBA5A – OCTOBER 2012 – REVISED NOVEMBER 2012 UNDERVOLTAGE LOCKOUT (UVLO) If at any time the voltage on the VM pins falls below the undervoltage-lockout threshold voltage, the device disables all outputs, resets internal logic, and drives the nFAULT pin low. Operation resumes when VM rises above the UVLO threshold. THERMAL INFORMATION Thermal Protection The DRV8313 has thermal shutdown (TSD) as previously described.
