TECHNICAL NOTE

Power Management LSI Series for Automotive Body Control

Regulators with

Voltage Detector and

Watchdog Timer

BD3004HFP,BD3005HFP

zDescription

The BD3004HFP,BD3005HFP low bias current regulator and watchdog timer features a high 50 V breakdown voltage and is compatible

with on-board vehicle microcontrollers. It offers an output current of 500 mA while limiting bias current to 80 µA (Typ.). The series supports

the use of ceramic capacitors as output phase compensation capacitors.The reset detection voltage can be changed by connecting a

resistor to the Vs pin.（BD3004HFP）The watchdog timer can be switched on and off using the INH pin input logic.（BD3005HFP）

zFeatures

1) 5 V/500 mA regulators for microcontrollers

BD3004HFP: Adjustable detection voltage (Vs pin)

BD3005HFP:Built-in watchdog timer reset circuit (INH pin: watchdog timer on/off)

2) Super-low bias current: 80 µA (Typ.)

3) Low-saturation voltage type P-channel DMOS output transistors

4) High precision output voltage: 5 V ±2%

5) Low-ESR ceramic capacitors can be used as output capacitors

6) Vcc Maximum applied voltage: 50 V

7) Built-in overcurrent protection circuit and thermal shutdown circuit

8) Built-in reverse connection breakdown prevention circuit

9) Back current flow protection during sudden battery failures, making it a highly reliable 5 V regulator.

10) HRP7 package

zApplications

Onboard devices (Vehicle equipment, Car stereos, Satellite navigation systems, etc.)
