MB3771 Datasheet Power Supply Monitor

Manufacturer: Cypress (now Infineon)

Overview: MB3771 Power Supply Monitor.

General 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 puter, for example.

If the circuit’s power supply deviates more than a specified amount, then the MB3771 generates a reset signal to the microprocessor.

Thus, the puter data is protected from accidental erasure.

Key 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.
