TB67S112PG Functional DescriptionRelation between logic inputs and output MOSFETs Logic input Output MOSFET IN1 IN2 OUT1 OUT2 L L Off Off H L On Off L H Off On H H On On Output pin for thermal shutdown signal (ERR output function) ERR Function H Normal operation L Thermal shutdown (TSD): active Note: ERR pin is the Nch MOS output pin of open drain type. When using this function, please pul up the ERR pin to VIN(H) level. It is in the Hi-Z state (internal MOS = OFF) in the normal operation. It outputs low (internal MOS = ON) when the thermal shutdown (TSD) is active. When the thermal shutdown detection is cleared, the ERR pin outputs high level again (internal MOS = OFF). Moreover, when the ERR pin is not used, please leave this pin open. VIN(H) level Pull-up resistor (10 kΩ to 100 kΩ) Output (ERR) pin for thermal ERR logic shutdown signal [MOSFET for thermal shutdown signal] ON: TSD is active. OFF: Normal operation 6 2019-07-08
