BD3021HFP-M

●Description

BD3021HFP-M is a regulator IC with integrated WDT (Watch Dog Timer), high output voltage accuracy ±2.0% and 80µA

(Typ.) low circuit current consumption. BD3021HFP-M supports usage of low ESR ceramic capacitor for output stability.

BD3021HFP-M can be a stable power supply for any applications while detecting malfunction of microcontrollers.

●Features

1) WDT Can be Switched ON/OFF by Using INH Pin

2) Low Circuit Current: 80µA(Typ.)

3) Output Circuit: Pch DMOS

4) High Output Voltage Accuracy: 5V±2%

5) Supports Low ESR Ceramic Capacitor

6) Vcc Max Voltage: 50V

7) Integrated Over Current Protection and Thermal Shut Down

8) HRP7 packaging

●Applications

Any application using a microcontroller or a DSP such as automotive (body control), display, server, DVD, phone, etc…
