News Release from: Linear Technology Corp | Subject: LTC1728H-5 voltage monitor
Edited by the Electronicstalk Editorial Team on 20 August 2007
Tiny voltage monitor works down to 1V
Drawing only 10uA from the supplies it monitors, the LTC1728H-5 provides a low power, reliable solution for high-temperature, space-limited applications.
Linear Technology has introduced the LTC1728H-5, a tiny, accurate triple supply voltage monitor that guarantees operation across -40C to 125C The LTC1728H-5 monitors 5V, 3.3V and one adjustable trip threshold set with an external resistive divider network, giving users the flexibility to monitor voltages as low as 1V

The LTC4557 is a dual SIM/smart-card power supply and level translator, which provides both 1.8 and 3V SIM power and digital signal level shifting from a 3 x 3mm QFN package.
Offered in a tiny 5-lead SOT-23 package, the LTC1728 is the smallest triple supply monitor available.
Drawing only 10uA from the supplies it monitors, the LTC1728H-5 provides a low power, reliable solution for high-temperature, space-limited applications.
The LTC1728 offers a tight 1.5% threshold accuracy over which reset can occur, decreasing the overall voltage margin required for reliable system operation.
This, along with power supply glitch filtering, a feature shared by Linear Technology's entire family of dual, triple, quad, hex and octal supply monitors, ensures predictable reset operation without false triggering.
Whenever one of the three monitored voltages falls below its threshold, a common open-drain reset output asserts and remains low until all three supplies are in compliance for at least 200ms. Request a free brochure from Linear Technology Corp ...
