MIC59P50BV-TR

Overview

The MIC59P50BV-TR is a latch-based peripheral driver featuring eight parallel-input protected latched outputs. It integrates CMOS data latches with bipolar Darlington transistor drivers, supporting high-voltage loads up to 80V and delivering output currents of 500mA per channel. The device includes common control functions for CLEAR, STROBE, and OUTPUT ENABLE. Built-in protection circuitry addresses transient, over-current, thermal, and under-voltage conditions. It operates within a temperature range extending to 85°C and is housed in a SOIC-24 package.

Feature Summary

• Integrates eight independent channels with individual bipolar Darlington drivers for high-current switching capabilities
• Includes comprehensive fault protection mechanisms covering over-temperature, over-current, and under-voltage lockout
• Features status flag output to indicate operational faults or active states

Applications

• Industrial automation systems requiring high-side load driving
• Automotive lighting and accessory control modules
• General-purpose high-voltage peripheral interfacing

Procurement Notes

Verify the specific suffix 'BV' against the manufacturer's official datasheet to confirm pinout compatibility and voltage ratings. Ensure the 'TR' designation matches the required reel packaging format for automated assembly processes. Cross-reference the RoHS compliance status as indicated in distributor records, noting potential variations between Micrel and Microchip documentation eras. Confirm moisture sensitivity level requirements for storage and handling procedures prior to soldering.

Selection Notes

Select this component when designing circuits that require simultaneous control of multiple high-current loads from low-voltage logic interfaces. The integrated latching mechanism simplifies microcontroller I/O usage by maintaining output states without continuous signaling. Consider the 80V maximum rating and 500mA per-channel current limit to ensure adequate headroom for the intended load profile. Evaluate the thermal dissipation requirements given the bipolar driver structure and ambient operating conditions.

Part Context

This part belongs to the MIC59P50 family of latch-based peripheral drivers originally developed by Micrel, now part of Microchip Technology. The series provides robust solutions for driving inductive or resistive loads in harsh environments. The BV variant specifically denotes the package and temperature grade configuration. These devices bridge the gap between standard logic levels and high-power actuation needs.

Replacement Considerations

The MIC59P50BWM is a non-trimmed version of the same functional device in a tube package. Verify package compatibility when substituting TR (reel) variants with WM (tube) variants.
