TLE8209-1R SPI Controlled H-Bridge Driver IC – 8.6A Peak Output for Throttle & DC Motor Control

The TLE8209-1R is a fully integrated H-Bridge power driver IC designed for automotive motor control applications, including throttle control actuators and DC motor drivers. This device combines control logic, gate drive circuitry, and low RDS(ON) power MOSFET outputs in a compact 20-pin DSO package with an exposed thermal pad for efficient heat dissipation.

This driver operates over a wide supply voltage range from 4.5V to 28V, with logic supply requiring 4.4V to 5.25V. It is capable of delivering output currents up to 8.6A, making it suitable for demanding actuator applications such as electronic throttle control (ETC) and idle air control (IAC) valves.

The device features SPI communication interface for configuration and diagnostic reporting, enabling sophisticated control and real-time fault monitoring. Comprehensive protection mechanisms include over-temperature protection, under-voltage lockout, over-current protection, short-circuit protection, and thermal shutdown, ensuring reliable operation in harsh automotive environments.

Key applications for the TLE8209-1R include throttle control actuators, idle speed control valves, exhaust gas recirculation (EGR) valves, and various DC motor control functions in modern engine management systems. The device is qualified for automotive-grade operation over the -40°C to +150°C temperature range.

The integrated power stage with low on-resistance MOSFETs ensures efficient power delivery with minimal heat generation, while the SPI interface provides full configurability and diagnostic feedback for system-level optimization.
