Overview
The BD49L59G-TL is a voltage detector manufactured by ROHM Semiconductor, designed for monitoring single-input power supplies. It features a fixed threshold voltage of 5.9 V with an accuracy of 1%. The device utilizes a CMOS output type and provides a reset delay time of 100 us. It operates within a maximum supply voltage of 10 V and supports a wide operating temperature range from -40 C to +105 C. The component consumes a working power supply current of 900 nA and has a power dissipation rating of 700 mW. It is housed in an SSOP-3 package.
Feature Summary
- CMOS output configuration for digital interface compatibility
- High precision voltage detection with 1% accuracy
- Ultra-low power consumption suitable for battery-operated systems
Applications
- Portable electronic devices requiring low standby current
- Battery-powered equipment needing reliable voltage supervision
- General-purpose supervisory circuits in consumer electronics
Procurement Notes
Verify the specific suffix G-TL against the official ROHM datasheet to confirm package type and tape-and-reel specifications. Confirm that the 5.9V threshold aligns with system requirements. Check for RoHS compliance status as indicated in manufacturer documentation. Ensure availability status is reviewed as distribution channels may vary.
Selection Notes
Select this component when a fixed 5.9V threshold is required with minimal quiescent current. The SSOP-3 package offers space efficiency for compact designs. Consider the 100us reset delay for timing-sensitive applications. Verify that the CMOS output drives the subsequent logic levels correctly without external pull-ups.
Part Context
This part belongs to the BD49 series of voltage detectors from ROHM Semiconductor. These components are engineered for high reliability and low power operation.
