Description
The MB3790PF-G-BND is a single-chip IC designed to control power supplies to SRAM, logic IC, or other circuit devices and protect them against momentary power failures by using backup batteries. It has the function to switch the source of power to the primary or secondary backup battery when the power supply voltage drops below a predetermined level. Additionally, it outputs a reset signal when the power supply turns on or off or when a fault occurs. This model consumes only a minimal current and comes in a thin-type package, making it best suited for power supply control in memory cards and similar devices.
Specifications and Features
The MB3790PF-G-BND has the following specifications and features:
- Input circuit current consumption when non-loaded: 50 µA [typ]
- Output drive current: 200 mA [max]
- Resistance between input and output: 0.5 ohms [typ]
- Input power-down detection level: 4.2 V ± 2.5 %
- On-chip power-on reset circuit
- Primary battery voltage-down detection levels: 2.65 V, 2.37 V
Application Scenarios
The MB3790PF-G-BND is widely used in power supply control for memory cards and similar devices. Its primary function is to control the power supplies to SRAM, logic IC, or other circuit devices and provide protection against momentary power failures using backup batteries.
