The LTC2908 is a precision six-input supply monitor from Linear Technology, designed for systems requiring accurate monitoring of multiple supply voltages. This IC can monitor up to six inputs simultaneously, including fixed voltages like 3.3V, 2.5V, 1.8V, and 1.5V, along with two adjustable inputs (ADJ1, ADJ2) for the B1 variant. It features a guaranteed threshold accuracy of ±1.5% of the monitored voltage.
The device provides a power-up/down reset function with a 200ms reset time delay. The common reset output remains low until all monitored inputs have been in compliance for the specified delay. The minimum reset level is as low as 0.5V, and the maximum supply voltage is 7V. The IC operates with a low supply current of 50µA.
Available in compact packages such as 8-Lead SOT-23 (ThinSOT) and 3x2 DFN-8, the LTC2908 is suitable for space-constrained applications. Its inputs can be shorted together for systems with fewer than six supplies, and the open-drain RST output can be wired-OR for systems requiring more than six monitors. The operating temperature range is -40°C to 85°C.
