DATASHEET
APPLICATION NOTE: The TRIP_SET / VIN4 pin circuitry is designed to use a 1% resistor externally. Using a 1%
resistor will result in the Thermal / Critical Shutdown temperature being decoded correctly. If
a 5% resistor is used, then the Thermal / Critical Shutdown temperature may be decoded
with as much as ±1°C error.
VTRIP is the TRIP_SET
voltage
[1]
TMIN is the minimum
temperature based on the
range
