Infineon TLE985x H-Bridge driver IC with integrated Arm® Cortex®-M0

The TLE985x H-Bridge MOSFET driver IC product family is the perfect fit for compact and cost-effective motor control solutions. It targets automotive applications such as sunroofs, window lifts, power lift gates, and auxiliary pumps.

The TLE985x integrates a 32-bit Arm® Cortex®-M0 core, along with market-proven peripherals such as two sets of ADCs, an HV-MON, a LIN transceiver, and a current-controlled H-Bridge driver. This enables a very cost-effective solution on a system level.

Key features

• Arm® Cortex®-M0 MCU with up to 40MHz
• On-chip oscillator & PLL
• Up to 96 KB Flash memory with 4 KB RAM
• H-Bridge MOSFET driver with current driven output stages

Additional features

• One protected high-side switch
• 5 V power supply output
• Integrated LIN transceiver compatible with LIN standard 2.2 and SAE J2602 supports fast programming via LIN
• Cost and board space improvements
• The TLE985x family allows driving MOSFETs at VBATT ≥ 6V with a low number of external components, providing a very cost-effective solution on a system level
• MOSFET driver with adaptive control (Infineon patent)
• Optimization of the system concerning EME (slow slew rates) and Pdiss (short dead times) simultaneously.
• Enable high levels of system reliability
• Extensive diagnostics and protections are embedded within the System-on-Chip (SoC)

Applications

• Automotive Motor Control for DC motors
• Single phase BLDC
