New Japan Radio NJW4113-T1
NJW4113-T1
Io=500mA LDO with Watchdog Timer
GENERAL DESCRIPTION
The NJW4113 is a 500mA output low dropout voltage regulator
with watchdog timer(WDT).
It has a detecting circuit to monitor output voltage and a watchdog
timer function for clock monitor. Detecting voltage is adjustable with
external resistor.
Low consumption current characteristic contributes to reduce
burden on automotive battery in full-time operating application.
Because of operating wide temperature range from -40°C to
+125°C, the NJW4113 suits for high reliability application such as
automotive application.

FUNCTION
Clock Input pin. Monitor the clock from CPU.
For Adjusting Detection Voltage pin.
It can optionally adjust Detection Voltage by connecting resistor divider.
If it is not required, this pin should be “open”.
Connects Capacitor pin for setting WDT Monitor Time, WDT Reset Time and Output
Delay Hold time.
It can optionally set time by external capacitor.
Power Supply pin.
Output Voltage pin.
GND pin.
Enable pin for WDT.
When the High level is WDT active while Low level or OPEN is WDT inactive.
Reset Output pin.
When output voltage is below the detection voltage, Output Low level signal.
VRO pin pulls up to VOUT internally with 100kΩ typ.
Connected to GND.
