TPS65735RSNR

The Texas Instruments TPS65735RSNR is a specialized Power Management Unit (PMU) tailored for active shutter 3D glasses. This IC integrates a comprehensive power solution including a power path, a linear charger with pre-charge, fast charge, and charge termination phases, a low-dropout regulator (LDO), and a boost converter.

The LDO provides a continuous output current of up to 30 mA, suitable for supplying external modules like microcontrollers or RF components. The boost converter offers an adjustable output voltage ranging from 8 V to 16 V and its output is internally connected to H-bridge analog switches. These switches are controlled by an external microcontroller for managing left and right shutter operations.

The device operates within an input voltage range of 2.5 V to 6.4 V and features a low quiescent current of 0.0086 mA. It is available in a 32-QFN (4x4 mm) package, designed for surface mounting. The operating temperature range is -40°C to 85°C.

Key features include power good and power sequencing capabilities, an externally set charge current supporting up to 100 mA, and LED current sinks for status indication. An output pin provides a divided-down battery voltage, useful for ADC or comparator inputs on an MCU.
