LSF0204QPWRQ1 General Description

LSF0204QPWRQ1 is a 4-channel bidirectional voltage translator with an integrated LDO regulator. It is specifically designed for automotive applications, making it ideal for use in environments with harsh operating conditions. The device features a wide input voltage range of 1.2V to 5.5V, allowing for compatibility with a variety of different voltage levels.LSF0204QPWRQ1 also has a low quiescent current, making it suitable for battery-powered applications where power consumption is a concern. It provides level shifting functionality between different voltage domains, allowing for seamless communication between different components with varying voltage levels.Additionally, the integrated LDO regulator provides a stable output voltage for powering other devices in the system. This eliminates the need for an external voltage regulator, reducing overall component count and board space.

Key Features

Quad low-supply-voltage translator/synchronizer

Integrated voltage-level shifting and synchronization for signal integrity

Wide voltage translation range: 0.9 V to 3.6 V

Ultra-low supply current: 0.5 μA
