TC642BEUA

Overview

The TC642BEUA is a brushless DC motor controller and driver from Microchip Technology's FanSense series. It operates on a supply voltage range of 3V to 5.5V and features an integrated low-side pre-driver output configuration. The device supports PWM control interfaces and includes fault detection capabilities. It is housed in an 8-MSOP package with dimensions of 3.1mm x 3.1mm x 0.97mm. The component functions within a temperature range of -40°C to +85°C and draws a typical operating supply current of 1 mA.

Feature Summary

• Integrates a dedicated low-side pre-driver for brushless DC motor applications
• Includes built-in fault detection mechanisms for system protection
• Supports PWM-based speed control interfaces

Applications

• Fan controllers
• Brushless DC motor control systems
• Motion control applications

Procurement Notes

Verify the specific suffix 'BEUA' corresponds to the MSOP tube packaging variant, distinct from tape-and-reel options like 'BEOA'. Confirm RoHS compliance status and check for End-of-Life notifications, as discontinuation notices have been issued for related family members. Ensure lead times align with current production schedules before finalizing orders.

Selection Notes

Select this component when designing compact BLDC motor drives requiring low quiescent current and integrated fault handling. The 8-MSOP package suits space-constrained PCB layouts. Compare against TC642EUA for pinout compatibility or TC646BEUA if over-temperature alert features are required instead of standard fault detection.

Part Context

This part belongs to the TC642 family of motor controllers designed for fan and small BLDC applications. It complements other Microchip solutions like the TC646 and TC648 series, offering specialized low-side driving with fault monitoring. The FanSense branding indicates optimization for thermal management and efficiency in cooling systems.
