LTC2938HMS#PBF, Supervisory Circuits Con?gurable 4-S Mon s w/ Watchdog Time

Power\Power Management ICs\Supervisory Circuits LTC2938 is a configurable supply monitor with watchdog timer. 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. This also features 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. Each status output has a weak internal pull-up and may be externally pulled up to a user-defined voltage. • Simultaneously monitors four supplies • Guaranteed threshold accuracy is ±1.5% • Adjustable reset and watchdog timeout • Power supply glitch immunity • Guaranteed active-low RST for VCC > 1V • Watchdog timeout period is 40ms at CWT = 1500pF, TA = 25°C, VCC = 5V • 12-lead plastic MSOP package • Temperature range from -40°C to 125°C
