Temperature switch integrates safety latch
Seiko Instruments has developed the S-8130 Series temperature switch with latch
The S-8130 inverts the output signal when the temperature limit is reached and latches until a reset signal is input or it detects that the power voltage has been lowered. This temperature switch was designed for use in game consoles, notebook computers and desktop PCs. Thanks to CMOS technology, the S-8130 Series, S-8130AA and S-8130AC, features a low quiescent current of 15uA, low voltage operation of 2.2V minimum, and wide operation temperature of -40 to +100C.

Chip drives three LEDs for backlighting
New from Seiko Instruments, the S-8813 Series three-channel white LED driver is a CMOS charge pump IC with a built-in constant-current circuit
The S-8130 consists of a temperature sensor with a temperature coefficient of -13mV/C, a comparator, voltage detection circuit and noise suppression circuit all of which are enclosed in a small 8-pin MSOP package.
The detection temperature of the S-8130AA is fixed in 5C increments from +60 to +95C, whereas the S-8130AC has a variable detection temperature, set by an external reference voltage in the circuit.
The S-8130 Series is available now and is priced at $0.70 each in quantities of 10,000 through a network of authorised distributors.
Samples are available for some versions in the series.
