DEMOBOARD TLE8201R Infineon

Door Module Power IC TLE 8201R Data Sheet Rev. 2.0 Features Full bridge (150m ) for main doorlock motor Two half-bridges (400m ) for deadbolt and mirror position motor or mirror fold motor Two half-bridges (800m ) for mirror position High-side switch (100m ) for mirror defrost Four high-side switches (500m ) for 5W and 10W lamps Current sense analog output with multiplex All outputs with short circuit protection and diagnosis Over-temperature protection with warning Open load diagnosis for all outputs Charge pump-Output for n-channel MOS-FET reverse-polarity protection Very low current consumption in sleep mode Standard 16-bit SPI for control and diagnosis Over-and Undervoltage Lockout Power-SO package with full-size heatslug for excellent low thermal resistance Type Ordering Code Package/Shipment TLE 8201R - PG-DSO-36-27 Functional Description The TLE 8201R is an Application Specific Standard Product for automotive door-module applications. It includes all the power stages necessary to drive the loads in a typical front door application, i.e. central lock, deadlock or mirror fold, mirror position, mirror defrost and 5W or 10W lamps, e.g for turn signal, courtesy/warning or control panel illumination. It is designed as a monolithic circuit in Infineons mixed technology SPT which combines bipolar and CMOS control circuitry with DMOS power devices. Short circuit and over-temperature protection and a detailed diagnosis are in line with the safety requirements of automotive applications. The current sense output allows to improve the total system performance. The standard SPI interface saves microcontroller I/O lines while still giving flexible control of the power stages and a detailed diagnosis.
