The A4412KLVTR-T from Allegro Microsystems is a versatile power management integrated circuit (PMIC) designed for automotive applications, particularly under-hood environments. It utilizes a buck or buck-boost pre-regulator to efficiently convert automotive battery voltages into tightly regulated intermediate voltages.
This device integrates multiple power outputs, including a 3.3V linear regulator, three 5V linear regulators (one with short-to-battery protection), and an adjustable 400mA synchronous buck regulator. The synchronous buck regulator operates at 2.2MHz and offers features like pulse-by-pulse current limit, hiccup mode short-circuit protection, and thermal shutdown.
The A4412KLVTR-T is supplied in a 38-lead eTSSOP package with an exposed power pad, measuring a maximum height of 1.2mm. It supports surface mount installation and operates across a wide temperature range of -40°C to 150°C. The IC includes diagnostic outputs, a window watchdog timer, and control capabilities via a serial peripheral interface (SPI).
Designed for high-temperature environments, this PMIC is ideal for supplying power to CAN transceivers, sensors, and microprocessors. Its ASIL D safety element out-of-context (SEooC) compliance and AEC-Q100 qualification make it suitable for safety-critical automotive systems.
