LTC2903IS6-A1#TRMPBF

LTC2903IS6-A1#TRMPBF is a precision quad supply monitor. It monitors up to four supply voltages. The common reset output remains low until all four inputs have been in compliance for 200ms. Voltage thresholds maintain ±1.5% accuracy over temperature (with respect to the monitored voltage). It features an open-drain RST output with a weak internal pullup. The active-low RST output is guaranteed to sink at least 5µA (VOL = 0.15V) for VCC down to 0.5V and will typically conduct current down to 0V. Quiescent current is 20µA typical, making this ideal for power conscious systems. Typical applications include multi-voltage systems, optical networking systems, cell phone base stations, network servers.

• Ultralow voltage reset: VCC = 0.5V guaranteed
• Guaranteed threshold accuracy: ±1.5% of monitored voltage over temperature
• Active low open-drain active-low RST output, power supply glitch immunity
• V1 input current is 25µA typical at (V1 = 5V, TA = 25°C)
• Reset time-out period is 200ms typical at (TA = 25°C)
• 150µs typical VX undervoltage detect to active-low RST at (TA = 25°C)
• 5mV typical output voltage low active-low RST at (VCC = 0.2V, IRST = 0.1µA)
• Operating temperature range from -40°C to 85°C
• 6-lead plastic TSOT-23 package
