HA1848P - Watchdog Timer

General Description

The HA1835P and HA1848P is a monolithic voltage regulator control designed for microcomputer systems.

In addition to the voltage regulator, it include watchdog timer function and power-on reset function.

These ICs can perform many function in various microcomputer systems with few external parts.

Key Features

  • Regulated power supply control function  Wide area of operational voltage; V CC = 6 V to 30 V  Available external PNP-type transistor, suited to any system power supply  Built-in overcurrent limiter for external PNP-type transistor  Output voltage can be adjusted exactry in the range from 4 V to 6 V.
  • Watchdog timer  Internal bandpass filter control circuit (pulse width detect type) and reset signal oscillator  Fail-safe utility  Bandpass filter characteristics can be se.
