Door Module Power IC 36-Pin DSO

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.

• Full bridge (150m?) for main door lock 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 Under voltage Lockout
• Power-SO package with full-size heat slug for excellent low thermal resistance
