Overview
The BD48L55G-TL is a voltage detector IC from ROHM Semiconductor designed for monitoring single power supply lines. It features an N-channel open-drain output and operates within a maximum supply voltage of 10 V. The device detects voltages with a threshold of 5.5 V and maintains an accuracy of 1%. It consumes a typical operating current of 900 nA and includes a reset delay time of 100 us. The component functions reliably across a temperature range of -40 C to +105 C and is housed in an SSOP-3 package.
Feature Summary
- Provides precise voltage supervision with 1% detection accuracy
- Features ultra-low power consumption suitable for battery applications
- Utilizes compact SSOP-3 surface-mount packaging
Applications
- Monitoring microprocessor power supplies
- Battery backup system supervision
- Embedded circuit protection
Procurement Notes
Verify the obsolete status and last-time-buy availability directly with authorized distributors or the manufacturer. Confirm that the SSOP-3 package dimensions and pinout match the target design requirements before finalizing procurement plans due to potential supply chain constraints.
Selection Notes
Select this component when a 5.5 V threshold is required for single-input voltage monitoring. Ensure the application supports open-drain outputs and does not require manual reset functionality. Verify compatibility with the specified operating temperature range and supply voltage limits during the design phase.
Part Context
This part belongs to the BD48xxx series, which offers N-channel open-drain outputs. It complements the BD49xxx series that provides CMOS outputs. Both series share similar low-current characteristics and are intended for supervisory roles in portable and industrial electronics requiring reliable voltage tracking.
