LTC2939 - (LTC2938 / LTC2939) Configurable 4- and 6-Supply Monitors

Download the LTC2939 datasheet PDF. This datasheet also covers the LTC2938 variant, as both devices belong to the same (ltc2938 / ltc2939) configurable 4- and 6-supply monitors family and are provided as variant models within a single manufacturer datasheet.

General Description

The LTC®2938/LTC2939 are configurable supply monitors for systems with up to four or six supply voltages that need watchdog supervision.

One of sixteen preset or adjustable voltage monitor combinations can be selected using an external resistive divider connected to the program input.

LTC2938/LTC2939 Configurable 4- and 6-Supply Monitors with Watchdog Timer FEATURES n n DESCRIPTION The LTC®2938/LTC2939 are configurable supply monitors for systems with up to four or six supply voltages that need watchdog supervision. One of sixteen preset or adjustable voltage monitor combinations can be selected using an external resistive divider connected to the program input. The preset voltage thresholds are accurate to ±1.5% over temperature. The LTC2938 and LTC2939 also feature adjustable inputs with a 0.5V nominal threshold. The reset and watchdog timeout periods are adjustable using external capacitors. Tight voltage threshold accuracy and glitch immunity ensure reliable reset operation without false triggering.
