Product Description

STMicroelectronics L9963T-TR is a Battery Backup IC designed for power management applications requiring robust communication across different voltage domains. This device operates with an input voltage range from 3.3 V to 5 V, providing a regulated 1.4 V output at 18 mA current in a compact SO-16N 64-pin surface mount package.

The L9963T-TR facilitates a seamless SPI communication bridge, converting signals between a conventional 4-wire SPI interface and a 2-wire isolated interface suitable for industrial, automotive, and embedded systems. It supports both transformer and capacitive isolation methods to ensure signal integrity in noisy or high-voltage environments.

Qualified to AEC-Q100 standards and fully ISO26262 ASIL-D compliant, this IC is engineered for high reliability in automotive safety-critical applications. It withstands operating temperatures from -40°C up to 105°C, making it suitable for harsh industrial and automotive environments.

The device’s dimensions, 10 mm in length and 1.25 mm in height, and its 64-pin SO-16N package enable space-efficient PCB layouts in complex electronic assemblies. It supports both 3.3 V and 5 V logic, providing versatile compatibility with a wide range of digital control systems.

Typical use cases include automotive battery management, industrial communication interfaces, isolated data transmission, and embedded system power backup solutions. It is an essential component in power management IC portfolios, ensuring uninterrupted system operation during power disturbances.
