OPTIREG™ TLE9744QK Traction Inverter PMIC

Infineon Technologies OPTIREG™ TLE9744QK Traction Inverter Power Management Integrated Circuit (PMIC) is a system chip that includes complete power-supply functionality and application-specific features for high-voltage main traction inverter systems. The power supply includes two pre-regulators to supply separate integrated linear regulator rails for the microcontroller supply, the communication supply, and a precise voltage reference. Two voltage trackers are available to supply off-board sensors. For functional safety support, a safety switch driver for the external N-channel MOSFET power switch is integrated, along with a charge pump that can also supply active reverse-polarity protection circuitry. The Infineon TLE9744QK includes a window watchdog and a functional watchdog, AURIX™ FSP monitoring, low-voltage monitoring, and bidirectional reset/interrupt input/output. Developed according to ISO 26262, this PMIC targets systems up to ASIL D, and supports a junction temperature of up to +150°C.
