PRODUCTION DATA

7.3.1 TMP390 Programming Tables

The temperature threshold and hysteresis options for the TMP390 device are programmed using two external 1% E96 standard resistors. The specific resistor value to ground on the SETA input sets the temperature threshold of channel A. The specific resistor value to ground on the SETB input sets the temperature threshold of channel B, as well as the hysteresis for both channel A and channel B.

CHANNEL A (HOT) TRIP TEMPERATURE (°C)	CHANNEL A NOMINAL 1% RESISTORS (KΩ)	CHANNEL A (HOT) TRIP RESET TEMPERATURE (°C) FOR HYSTERESIS = 5°C	CHANNEL A (HOT) TRIP RESET TEMPERATURE (°C) FOR HYSTERESIS = 10°C

Note:

When the SETA pin is grounded or left floating during the device power up, the OUTA pin always stays low. The Channel B functionality is not affected by the SETA channel.
