The TPIC7218-Q1 device integrates in single package several functions needed in ABS and ESC electronic control units (ECU). This integration coupled with the minimization of the external components saves valuable ECU board space.

The TPIC7218-Q1 device is an antilock braking controller capable of directly driving eight solenoid valves with internal high-current low-side drivers. Low-side drivers configured for digital control do not require external voltage clamps. The TPIC7218-Q1 device has gate drive capability for two high-side N-Channel MOSFETs that can be used to drive a pump motor and power to all solenoids. The TPIC7218-Q1 device provides a fault-tolerant interface for both Intelligent and Active wheel-speed sensors to an external microprocessor. The TPIC7218-Q1 device can be used with either 3.3- or 5-V microprocessors and uses a standard SPI (Serial-Peripheral Interface).

The TPIC7218-Q1 device has two internal open-drain warning lamp drivers that can be pulled up to battery voltage, as well as one low-voltage driver. An internal state machine monitors a watchdog input and reports faults on a warning-lamp pin and SPI register. A K-Line transceiver is also included. A multitude of safety and fault monitoring functionality supervise both system and TPIC7218-Q1 circuits. Faults must be polled and reset over SPI. The TPIC7218-Q1 device is designed for use in harsh automotive environments, capable of withstanding high operating temperatures and electrically noisy signals and power. Short-to-ground, short-to-battery, and open-load conditions are tolerated and monitored. The TPIC7218-Q1 device also exhibits outstanding Electro-Magnetic Compatibility (EMC) performance.
