O3853AQDCARQ1 Description

Short technical summary and product information.

The O3853AQDCARQ1 is an automotive high voltage power management IC from Texas Instruments. It features a synchronous buck-boost preregulator that produces a 6V output and an LDO capable of delivering a 5V output at up to 285 mA. The device is designed for battery-powered automotive applications requiring robust power conditioning.

 

The input voltage range is specified under multiple conditions: initial battery power-up requires a minimum of 7 V, after which full functionality is maintained from 4 V to 36 V. During operation after wake-up, the input can drop as low as 2.3 V. This wide input range makes the part suitable for automotive systems with fluctuating battery voltages.

 

The IC integrates internal FETs for the buck-boost converter, reducing external component count. It is categorized under Power Management (PMIC) and is specialized for automotive environments. No package or operating temperature details are provided in the available specifications.
