BD42500G-CTR

Power Management - Specialized Overview

The BD42500G-CTR is a voltage tracker IC from Rohm Semiconductor, designed for automotive applications. It features a withstand voltage of 45V, an input voltage range of 3V to 45V, and a maximum output current of 50mA. The device offers high accuracy with a bias voltage of ±15mV and low quiescent current of 40µA. It operates within a junction temperature range of -40°C to +150°C and includes thermal shutdown and overcurrent protection. The component is AEC-Q100 qualified and housed in an SSOP-5 package.

Power Management - Specialized Feature Summary

• Integrated overcurrent and thermal shutdown protection circuits prevent damage from short circuits or overload conditions.
• Supports ceramic capacitors for output phase compensation, simplifying external circuit design.
• Low standby current consumption suitable for battery-direct systems requiring power efficiency.

Power Management - Specialized Applications

• Automotive electronic control units
• Battery-connected system power management
• Voltage tracking in automotive PMIC architectures

Power Management - Specialized Procurement Notes

Verify the specific suffix 'CTR' indicates the cut tape packaging format as documented by the manufacturer. Confirm AEC-Q100 qualification status aligns with project requirements. Ensure the SSOP-5 footprint matches the PCB layout specifications. Cross-reference the datasheet revision date to confirm compatibility with existing design parameters.

Power Management - Specialized Selection Notes

Select this component when a wide input voltage range up to 45V is required alongside precise voltage tracking. The low quiescent current makes it suitable for always-on automotive circuits. Verify that the SSOP-5 package fits the available board space. Consider the thermal performance given the 150°C maximum junction temperature rating for harsh environments.

Power Management - Specialized Part Context

This part belongs to Rohm's professional power management (PMIC) family, specifically targeting automotive-grade voltage regulation. It functions as a voltage tracker rather than a standard LDO, allowing it to follow a reference voltage while handling higher input voltages. The series is designed to meet stringent automotive reliability standards.

Power Management - Specialized Replacement Considerations

Public documentation does not list direct substitute part numbers for the BD42500G-CTR. Designers should consult official Rohm resources for potential obsolescence notices or recommended alternatives if supply constraints arise.
