S-5840B Series www.sii-ic.com TEMPERATURE SWITCH IC (THERMOSTAT IC) WITH LATCH © Seiko Instruments Inc., 2007-2012 Rev.2.1_00 The S-5840B Series is a temperature switch IC (thermostat IC) with a latch function which detects the temperature with a temperature accuracy of ±2.5°C.

When the temperature reaches the detection temperature, the output signal is inverted and being latched until the S-5840B Series detects decrease in a power supply voltage.

The S-5840B Series operates at the lower po
