HA1848P
Overview
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.
- 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 set by external resister (Rf) and capacitance (Cf)
- Automatic reset Automatic power-on reset Pulse generator characteristics can be set by external resistor (RR) and capacitance (CR) Alternative between RES and RES output
