Overview
The Infineon TLE9861QXA20XUMA4 is an automotive-grade System-on-Chip (SoC) featuring a 32-bit Arm Cortex-M3 core operating at up to 24 MHz. It integrates 36 KB of flash memory, 3 KB of RAM, and a high-side/low-side H-bridge MOSFET driver with an integrated charge pump. The device supports a single power supply from 5.5 V to 27 V and operates within a junction temperature range of -40°C to +150°C. Key peripherals include a 10-bit ADC, multiple timers, UART, SSC interfaces, and a high-speed operational amplifier for motor current sensing.
Feature Summary
- Integrated H-bridge MOSFET driver with charge pump
- Arm Cortex-M3 core with 36 KB flash and 3 KB RAM
- High-speed operational amplifier for shunt-based current sensing
- Single power supply operation (5.5 V to 27 V)
Applications
- Windshield wiper systems
- Auxiliary pumps and fans
- Window lift actuators
- Sunroof drives
- Tailgate control modules
Procurement Notes
Verify the specific ordering suffix XUMA4 corresponds to the UI step package variant as defined in the official datasheet table. Confirm that the required voltage range and thermal specifications align with the target application environment before finalizing procurement.
Selection Notes
Select this component for applications requiring an integrated microcontroller and power stage for brushed DC motor control. Ensure the design accommodates the 48-pin VQFN package and utilizes the internal charge pump for gate driving without external bootstrap components.
Part Context
This part belongs to the MOTIX™ family of automotive microcontrollers designed for body applications. It consolidates processing, communication, and power drive functions into a single chip to reduce system complexity and bill of materials for standard automotive loads.
Replacement Considerations
Datasheet documentation lists TLE9861QXA20XUMA2 and TLE9861QXA20XUMA3 as alternative orderable part numbers for the same functional device. Verify package compatibility when substituting between these variants.
