Seiko Instruments S-5840B
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 power supply voltage of 1.0 V and its current consumption is 12 μA typ.| Part No. | S-5840B |
