BD5346G-TR

Overview

The BD5346G-TR is a CMOS reset IC featuring an adjustable delay timer, manufactured by Rohm Semiconductor. It operates within a supply voltage range of 0.8V to 6V with a typical under-voltage detection threshold of 4.6V and ±2.5% precision. The device delivers low power consumption, drawing 0.23µA in the ON state and 0.27µA in the OFF state. It utilizes an SSOP-5 package and supports an operating temperature range from -40°C to 105°C.

Feature Summary

• Adjustable delay time setting via external capacitor
• CMOS output type for direct logic interfacing
• Ultra-low current consumption suitable for battery applications

Applications

• Microprocessor system reset circuits
• Battery-powered electronic devices
• Portable consumer electronics requiring low standby current

Procurement Notes

Verify the specific suffix 'TR' indicates tape-and-reel packaging when sourcing. Confirm RoHS compliance status matches current manufacturing standards. Ensure the SSOP-5 footprint aligns with PCB design requirements before finalizing procurement orders.

Selection Notes

Select this component when an adjustable reset delay is required without manual reset functionality. Compare against open-drain variants if higher drive capability or different output logic levels are necessary for the target application circuit.

Part Context

This part belongs to Rohm's Nano Energy series of CMOS voltage detectors. It complements the BD52xx-2M series, which offers N-ch open-drain outputs instead of CMOS. Both series share similar low-power characteristics and adjustable delay capabilities within the same package family.

Replacement Considerations

BD5246G-1 serves as a pin-compatible alternative with open-drain output. BD5343G is a discontinued predecessor with similar specifications but lower accuracy. Verify functional equivalence regarding output stage and delay adjustment methods before substitution.
