TLE84106EL and TLE84110EL – New Drivers for Small DC Motors

TLE84110EL Application Diagram

The TLE84106EL and TLE84110EL are protected half-bridge driver ICs designed to driver 3 to 5 DC motors in parallel mode or 5 to 9 DC motors in sequential mode. The drivers are designed for DC motors used to drive ventilation flaps in HVAC systems. Device control and diagnosis are done via a 16-bit SPI interface. The extensive 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 (body size 8.65x3.9mm) provides good thermal performance and reduces PCB-board space and costs.
