Overview
The BD48K51G-TL is a voltage detector manufactured by ROHM Semiconductor, designed for monitoring single-channel power supply voltages. It features an open-drain output type and operates within a supply voltage range up to 10 V. The threshold voltage is specified at 5.1 V with a precision of ±1%. The device includes a reset delay time of 100 µs and consumes a typical operating current of 900 nA. It supports surface mount installation in a 3-SSOP package and functions reliably across an extended temperature range from -40°C to +105°C.
Feature Summary
- Provides precise voltage supervision with high accuracy for reliable system monitoring
- Features low power consumption suitable for battery-operated applications
- Utilizes an open-drain output configuration for flexible interface compatibility
Applications
- Single-channel power supply monitoring in electronic circuits
- Voltage supervision for microprocessor reset systems
- Battery backup detection in portable devices
Procurement Notes
Verify the specific suffix and package variant against the official datasheet before procurement. Confirm availability status as distribution channels may list obsolete or discontinued stock. Ensure the ordering part number matches the required tolerance and thermal specifications for your application environment.
Selection Notes
Select this component when a fixed 5.1 V threshold is required for voltage supervision. Consider the 3-SSOP package constraints for PCB layout. Verify that the open-drain output aligns with the input requirements of the downstream logic or microcontroller reset pin.
Part Context
This component belongs to the BD48Kxx series of voltage detectors from ROHM Semiconductor. The series offers various threshold voltages while maintaining consistent low-power characteristics and compact packaging options for modern electronic designs.
Replacement Considerations
The BD5250G-1TR is listed as a similar specification replacement with comparable voltage detection capabilities. Verify pinout compatibility and electrical parameters before substitution.
