MIC2791H-04VMT集成电路（IC）的监控器规格书PDF中文资料

General Description

The MIC2790/1/3 is ideal for monitoring highly-accurate core voltages that require rapid response in the event of a fault condition. The voltage supervisor IC features a manual reset input, enable input (MIC2793 only), a capacitor-programmable reset timeout delay and both an active-low and active-high reset output.

Features

• 1.5V to 5.5V operating supply voltage range

• Ultra-fast propagation delay (1µs typically)

• 0.4V reference voltage (SNS pin)

- ±1.0 threshold accuracy from 40°C to +125°C

- Monitored voltage range from 0.4V to 5.5V

• Programmable reset timeout delay (from 1ms to 10s)

• Manual reset input with an internal pull-up resistor

• Active-high enable input pin (MIC2793 only)

• The MIC2790/1/3 features multiple output options:

 Open-drain active-low (/RESET)

- Push-pull active-low (/RESET)

- Push-pull active-high (RESET)

• -40°C to 125°C junction temperature range

• 6-pin TSOT-23 (MIC2790)

• 6-pin 2mm × 2mm Thin DFN (MIC2790)

• 6-pin 1.6mm × 1.6mm Thin DFN (MIC2791)

• 8-pin 2mm × 2mm Thin DFN (MIC2793)

Applications

• Telecom

• Computer/servers

• Medical equipment
