2 / 9 page TPIC7218-Q1 SLDS182 – AUGUST 2010 www.ti.com 1.2 Description The TPIC7218 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 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 provides a fault tolerant interface for both Intelligent and Active wheel speed sensors to an external microprocessor. The TPIC218 can be used with either 3.3 or 5.0 V microprocessors and utilizes a standard SPI interface. The TPIC7218 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 circuits. Faults must be polled and reset over SPI. The TPIC7218 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 also exhibits outstanding Electro-Magnetic Compatibility (EMC) performance. ORDERING INFORMATION ORDERABLE PART TA PACKAGE(1) TOP-SIDE MARKING NUMBER –40°C to 125°C PowerPAD™ S-PQFP – G80 Reel of 1000 TPIC7218QPFRQ1 TPIC7218 (1) “Pb-Free” is defined to be compliant with the current RoHS requirements for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials unless exempt. Where designed to be soldered at high temperatures, TI "Pb-Free" and "RoHS Compliant" products are suitable for use in specified lead-free processes. 2 Introduction Copyright © 2010, Texas Instruments Incorporated Submit Documentation Feedback Product Folder Link(s): TPIC7218-Q1 |
