The TLE84106EL is a protected Hex-Half-Bridge-Driver designed especially for automotive motion control applications such as Heating, Ventilation and Air Conditioning (HVAC) flap DC motor control. It is par t of the MonolythIC family in Infineon’s Smart Power Technology SPT® which combines bipolar and CMOS control circuitry with DMOS power devices. The 6 half bridge drivers are designed to drive DC motor loads in sequential or parallel operation. Operation modes forward (cw), reverse (ccw), brake and high impedance are controlled from a 16-bit SPI interface. The diagnosis features such as short circuit, open load, power supply failure and overtemperature in combination with its low quiescent current makes this device attractive for automotive applications. The extremely small fine pitch exposed pad PG-SSOP-24-4 package in a SO -14 body provides good thermal performance and reduces PCB-board space and costs.
