Overview

TA8045BF TOSHIBA BIPOLAR LINEAR INTEGRATED CIRCUIT SILICON MONOLITHI TA8045BF 5V Voltage Regulator With Watchdog Timer This IC is designed especially for microcomputer system in automobiles and is capable of providing output voltage 5 ±0.
15V without any adjustment.
This IC incorporates the system reset function, that is, low voltage reset and watchdog timer which can self-diagnose the microcomputer system so that program runaway can be prevented.
This IC also has an over-voltage protection, current limiter and thermal protection to protect the IC from destruction caused of overstress and load accident.
In addition, this IC has a low standby current function, so it can be connected directly to an automotive battery.

Watchdog timer reset pin.
− Generates a reset signal which is determined by the CR combination of the TC pin.
− Intermittently generates reset pulses if no clock is supplied to the CK pin.
The RESET signal is the output from the collector of an NPN transistor with a pull-up resistor.
Clock input pin for the watchdog timer.
If it is used for a Power-on reset timer only, it is pulled up to RESET pin.
Pin for setting a time for the reset timer and ...
