Description
The Cypress MB3771 is designed to monitor the voltage level of one or two power supplies (+5 V and an arbitrary voltage) in a microprocessor circuit, memory board in large-size computer, for example.
Features
- Precision voltage detection (VSA = 4.2 V ± 2.5 %).
- User selectable threshold level with hysteresis (VSB = 1.23 V ± 1.5 %).
- Monitors the voltage of one or two power supplies (5 V and an arbitrary voltage, >1.23 V).
- Usable as over voltage detector.
- Low voltage output for reset signal (VCC = 0.8 V Typ).
- Minimal number of external components (one capacitor Min).
- Low power dissipation (ICC = 0.35 mA Typ, VCC = 5 V).
- Detection threshold voltage has hysteresis f.
