Voltage monitors check automotive supplies
All devices have threshold accuracy of +/-1.5% over the automotive temperature range, allowing them to accurately monitor single channel point-of-load or multichannel applications.
Two external resistors per input determine the desired trip point for the undervoltage monitor, while a three-state select pin programs the polarity combinations for the input thresholds, allowing negative supplies to be monitored.
Two complimentary reset outputs signal when any of the supplies are below operating range, while the input glitch filter ensures that there will not be false or noisy triggering.
Supervising a wide variety of voltages with great precision, the LTC2910 is ideal for a broad spectrum of multivoltage, high-density systems such as desktop and notebook computers, networking systems and wireless basestations.
The IC is offered in small 16-pin 5 x 3mm DFN and 16-pin SSOP packages.
Specified over the commercial and industrial temperature ranges and available from stock, the LTC2910 is priced at US $3.20 each in 1000-piece quantities. Request a free brochure from Linear Technology Corp ...
