Texas Instruments TPS2044B Quad Current-Limited Power Distribution Switches TPS2044BD

The TPS2044B is a quad current-limited power distribution switch designed for applications involving heavy capacitive loads and short-circuit protection. It features a high-side N-channel MOSFET with a low on-resistance of 70m,Ѷ, allowing for efficient power distribution. The device supports a continuous current of 500mA and operates within a voltage range of 2.7V to 5.5V. Key protective features include thermal shutdown and accurate current limiting, which is set between 0.75A and 1.25A. The TPS2044B also incorporates undervoltage lockout and a deglitched fault report output to indicate overcurrent conditions without glitches during power-up. The typical rise time is 0.6ms, and the device has a low standby supply current of 2OºA. It is rated for operation in ambient temperatures from -40¬8C to 85¬8C and is UL recognized, making it suitable for various applications requiring reliable power distribution.
