BD46332G-TR

Overview

The BD46332G-TR is a voltage detector manufactured by ROHM Semiconductor, designed for supervisory circuit applications. It features a fixed detection threshold of 3.3V with a precision of ±1%. The device provides a CMOS output type and includes a manual reset function. It operates within a supply voltage range of 0.95V to 10V and has a fixed delay timer of 200msec. The component supports low active reset states and offers hysteresis voltage defined as VDET x 0.05. Circuit current consumption is specified at 0.80μA (ON) and 0.85μA (OFF) at VDET=4.8V. Output currents are 1.2mA (Low Vol) and 5mA (High Vol). It is housed in an SSOP5 package (SOT23-5 reference) measuring 2.9x2.8mm with a thickness of 1.25mm, operating from -40°C to 105°C.

Feature Summary

• Fixed delay time supervision with manual reset capability
• CMOS output interface for digital logic compatibility
• High accuracy voltage detection with defined hysteresis

Applications

• Microprocessor system reset circuits
• Battery-powered device power management
• Embedded system voltage supervision

Procurement Notes

Verify the obsolete status and Last Time Buy availability through authorized distributors. Confirm RoHS compliance and package integrity upon receipt. Ensure design-in compatibility with existing PCB footprints and signal levels before final procurement decisions.

Selection Notes

Select this component when a fixed 3.3V threshold with CMOS output is required. Consider the 200msec fixed delay for timing requirements. Manual reset functionality distinguishes it from non-reset variants. Verify thermal performance within the -40°C to 105°C range for the specific application environment.

Part Context

This part belongs to the BD46 series of voltage detectors from ROHM Semiconductor. It shares the SSOP5 package form factor with related models like the BD5233G-1 but differs in output type and delay characteristics. The series focuses on compact supervisory solutions for portable electronics.

Replacement Considerations

BD5233G-1 is listed as a same-package alternative with adjustable delay and open-drain output. Verify electrical parameter differences and functional changes before substitution.
