1VCC_INVCC_OUTPVCC_IN (TIOL112): External 3.3-V or 5-V logic supply input pin. VCC_OUT (TIOL1123, TIOL1125): 3.3-V or 5-V linear regulator output
2NFAULTNFAULTO Fault indicator output signal to the microcontroller. A low level indicates either an over- current, an undervoltage supply or an overtemperature condition.
3RXRXOReceive data output to the local microcontroller
4TXTXITransmit data input from the local microcontroller. No effect if EN is low. Logic high sets low-side switch. Logic low sets high-side switch. Weak internal pull-up.
5ENENIDriver enable input signal from the local microcontroller. Logic low sets the CQ output at Hi-Z. Weak internal pull-down.
6ILIM_ADJILIM_ADJIInput for current limit adjustment. Connect resistor RSET between ILIM_ADJ and L-.
