Temperature of LVIC vs. VOT Output CharacteristicsInside ICTemperatureVOTSignalMCURef10kΩ (1) Connect 10kΩ to VOT pin if temperature monitoring function is utilized; otherwise if the VOT pin is left unconnected, the internal over- temperature shutdown function is used instead. (2) In the case of using VOT with low voltage controller like 3.3V MCU, VOT output might exceed control supply voltage 3.3V when temperature rises excessively. If system uses low voltage controller, it is recommended to insert a clamp diode between control supply of the controller and VOT output for preventing over voltage destruction. Figure 4.
