TPS2145IPWP Description

Short technical summary and product information.

The TPS2145IPWP from Texas Instruments is a versatile power management IC that combines two current-limited power distribution switches with an adjustable low-dropout (LDO) voltage regulator in a single package. This integration offers a compact power management solution, saving board space compared to discrete implementations. Each switch is a 340-mΩ N-channel MOSFET capable of delivering 200 mA of continuous current. The device operates over a wide voltage range of 2.9V to 5.5V and features CMOS- and TTL-compatible enable inputs for flexible control.

 

The integrated LDO provides a regulated output voltage, adjustable from 1V to 3.3V, and has a low dropout voltage of 0.35V. Independent thermal and short-circuit protection are provided for the LDO and each switch, enhancing system reliability. Overcurrent indicators with transient filters are also included. The TPS2145IPWP is designed for applications such as USB hubs and peripherals, PDAs, portable electronics, and DSP power sequencing.

 

This component is supplied in a 14-pin HTSSOP package, suitable for surface mounting. It operates across an ambient temperature range of -40°C to 85°C, making it suitable for various environmental conditions. The typical supply current is a low 75 µA, contributing to power efficiency in battery-operated devices.
