Overview
The MCP8024T-H/PT is a three-phase brushless DC (BLDC) pre-driver manufactured by Microchip Technology. It operates within an input voltage range of 6V to 28V and supports continuous output currents up to 0.5A per phase. The device integrates three operational amplifiers for sensor signal conditioning and functions across an ambient temperature range of -40°C to +150°C. Packaged in a 48-lead TQFP with an exposed thermal pad (7x7mm), it is designed for automotive applications requiring robust motor control interfaces.
Feature Summary
- Integrates three operational amplifiers for direct connection to Hall effect sensors
- Supports PWM-based commutation for three-phase BLDC motors
- Designed for high-temperature automotive environments
Applications
- Automotive cooling fan systems
- Electric power steering actuators
- Blower motor control units
Procurement Notes
Verify the specific suffix 'PT' confirms the tape-and-reel packaging format and the 'H' grade indicates the extended temperature rating. Confirm the 48-TQFP-EP package dimensions match your PCB footprint requirements. Ensure the design accounts for the exposed pad thermal management needs specified in the datasheet.
Selection Notes
Select this component when a dedicated pre-driver interface for Hall-sensor-based BLDC motors is required. It is suitable for designs needing integrated op-amps for sensor signal processing without external components. Consider the 0.5A current capability and 28V maximum voltage limit against load requirements.
Part Context
This part belongs to Microchip's MCP80xx series of motor drivers, specifically targeting automotive-grade applications. It serves as a bridge between microcontroller logic signals and power MOSFET gates, simplifying the design of three-phase motor control circuits in vehicles.
Replacement Considerations
Check for pin-compatible alternatives within the same family or from other manufacturers offering similar 3-phase BLDC pre-drivers with integrated op-amps. Verify that any substitute matches the 48-TQFP-EP package and -40°C to +150°C operating temperature range.
