Infineon TLE92108 Multi-MOSFET Driver Family
Designed to control up to 8 half-bridges with one packaged device.
The Infineon TLE92108 Multi-MOSFET Driver Series allows driving up to 8 half-bridges (up to 16 N-Channel MOSFETs) with one single driver IC, which provides a very cost-effective solution for system designs. Less pick & place costs, less required PCB space, housed in a compact VQFN-48 package, are all ways for customers to drive multiple half-bridges in DC motor control applications.
The AEC Q-100 qualified TLE92108 driver portfolio features a 24-bit Serial Parallel Interface (SPI) that enables configuration of the multi-MOSFET driver and is used to control the half-bridges. The SPI offers a wide range of diagnostic features such as the monitoring of the supply voltage, the charge pump voltage, temperature warning and over-temperature shutdown. Each gate driver monitors its external MOSFET drain-source voltage for hard-short circuit conditions, while the devices can observe the current passing through the integrated op amps providing configurable soft-short circuit detection, in both cases providing active latching hardware protection independent of any software measures.
The Infineon TLE92108 family is qualified according to AEC-Q100 and are designed to withstand the severe conditions of automotive applications.
