Pin Functions

PIN TYPE DESCRIPTION
NO. NAME
1 HYST Input Hysteresis control, digital input; connect to GND for 10°C or V+ for 2°C
2 GND Power Ground, connected to the back side of the die through lead frame; connect to system ground
3 VTEMP Output Analog output voltage proportional to temperature; leave floating or connect to a high impedance node.
4 V+ Power Supply input; connect to 2.7 V to 5.5 V with a 0.1-μF bypass capacitor.
5(1) OS Output Overtemperature Shutdown open-drain active low thermostat digital output; connect to controller interrupt, system/power supply shutdown; pullup resistor ≥ 10 kΩ
OS Output Overtemperature Shutdown push-pull active high thermostat digital output; connect to controller interrupt, system/power supply shutdown
US Output Undertemperature Shutdown open-drain active low thermostat digital output; connect to controller interrupt, system/power supply shutdown; pullup resistor ≥ 10 kΩ
US Output Undertemperature Shutdown push-pull active high thermostat digital output; connect to controller interrupt, system/power supply shutdown
(1) Pin 5 functionality and trip point setting are programmed during LM26 manufacture.
