Infineon’s TLE988x and TLE989x sequence of ICs mix a gate driver, microcontroller, communication interface, and energy provide on a single chip. Gadgets within the TLE988x sequence are H-bridge drivers for 2-phase brushed DC motor management, whereas ICs within the TLE989x sequence are 3-phase bridge drivers for brushless DC motors.
The N-channel MOSFET drivers make use of a 32-bit Arm Cortex-M3 microcontroller operating at as much as 60 MHz to allow the implementation of superior motor management algorithms. Their CAN FD transceiver operates at a velocity of two Mbps. Variants supply flash reminiscence sizes of 128 kbytes and 256 kbytes and assist read-while-write operation.
The drivers are AEC-Q100 certified, making them appropriate for automotive motor management purposes. Infineon’s adaptive MOSFET management algorithm compensates for the variation of MOSFET parameters within the system by mechanically adjusting the gate present to realize the required switching. Gadgets are additionally ISO 26262 (ASIL B) compliant, and a few variants have built-in cybersecurity.
Housed in in 7×7-mm TQFP packages, the TLE988x and TLE989x gadgets are presently in manufacturing and obtainable. Two variants in LQFP packages with 64 pins will observe in December 2023.
