Temperature Switch IC With Enable MM3588
Temperature Switch IC With Enable
Monolithic IC MM3588
Outline
This IC is a a temperature switch IC that senses the IC ambient temperature and switches the IC output from
the Low to the High level when there is a detected temperature.
With the hysteresis circuit,IC output level keeps High until the ambient temperature falls to hysteresis
temperature after detection.
The detection temperature can be selected in the range of 60°C TDET 90°C at 1.0°C steps using rank
expansion,with detection temperature accuracy of ±2.0°C.
Features
1. Low current consumption (Typ. 1.5µA)
2. With enable function pin
3. Low operating power supply voltage (Operating voltage 1.6~5.0V)
Package

2 : Testing pin is connected with the internal circuit for testing.
When resistance and capacity are connected with Testing pin, this product produce improper operating
signals. Please set Testing pin to the open state.
3 : If any inputs are left open, since the input potential is undefined, the output logic level will be undefined,
creating an unstable operating state. Connect CE pin with VDD pin, when it is not used.
