Typical Application
Description
The LTC2910 is an octal input voltage monitor intended for monitoring multiple voltages in a variety of applications. Each input has a nominal 0.5V threshold, featuring 1.5% tight threshold accuracy over the entire operating temperature range. Glitch filtering ensures reliable reset operation without false or noisy triggering.Polarity selection and a buffered reference allow monitoring up to two separate negative voltages. A three state input pin allows setting the polarity of two inputs without requiring any external components.
The LTC2910 provides a precise, versatile, space-conscious, micropower solution for voltage monitoring.
