Output pin for thermal shutdown detection signal (ERR output function)
ERR Function H Normal operation L Thermal shutdown detection (TSD): active Note: ERR pin is the Nch MOS output pin of open drain type. When using this function, please pull up the voltage level of the ERR pin to VCC. It is in the Hi-Z state (internal MOS = OFF) in the normal operation. It outputs low (internal MOS = ON) when the thermal shut down detection (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. VCC Pull-up resistor (10 kΩ to 100 kΩ)
Output (ERR) pin for thermal shutdown signal ERR logic [MOSFET for thermal shutdown signal] ON: TSD is active. OFF: Normal operation
