What are the main features of the L9369-TR?
The L9369-TR is an automotive-grade PMIC designed for motor control applications with functional safety support (ISO 26262). It integrates gate pre-drivers for external MOSFETs, precision current-sense amplifiers, multiple ADC channels, SPI control with CRC, programmable protection features, watchdog timer, and built-in diagnostics.
What is the L9369-TR used for?
It is mainly used in automotive motor control systems such as electric power steering (EPS), automotive pumps, HVAC blowers, and other safety-critical motor drive applications. It is also used in industrial motor control systems where high reliability, fault detection, and precise current monitoring are required.
Does the L9369-TR have alternative manufacturer and part numbers?
There is no exact drop-in replacement from a different manufacturer due to its high level of integration and automotive safety features. However, similar functional alternatives can be found in motor-control PMIC or gate driver + sensing solutions from companies like Texas Instruments, Infineon Technologies, and NXP Semiconductors. Replacement selection depends heavily on system architecture, safety requirements, and MOSFET configuration.
Is technical support available for this part?
Yes. Technical support is available through STMicroelectronics official channels and authorized distributors like Nantian Electronics. Support typically includes datasheets, application notes, design guidance, pin configuration information, and assistance with sourcing and replacement options.
