TPS2044AD Description

Short technical summary and product information.

The TPS2044AD from Texas Instruments is a high-side MOSFET power switch designed for applications with heavy capacitive loads and potential short circuits. This device incorporates four independent switches, each controlled by a logic enable input. It provides a continuous current of 500mA per channel and features independent thermal and short-circuit protection with an overcurrent logic output.

 

The switch operates within a voltage range of 2.7V to 5.5V and includes undervoltage lockout (UVLO) and CMOS/TTL-compatible enable inputs. The device has a typical Rds On of 80mOhm and a typical rise time of 2.5ms. It is housed in a 16-SOIC package suitable for surface mounting.

 

Key protection features include current limiting, over-temperature shutdown, and undervoltage lockout, ensuring reliable operation in demanding conditions. The TPS2044AD is designed for general-purpose switch applications where robust power management is required.
