Product details

The TPS22919DCKR is a single-channel, N-channel high-side load switch from Texas Instruments, rated for 1.5 A continuous output over a 1.6 V to 5.5 V load-voltage range. The 89 mOhm typical on-resistance keeps conduction loss under 200 mW at full load — well within the SC-70-6 package's thermal budget when the copper pad is sized per the datasheet layout.

Industrial temperature grade and environment

The 1.6 V minimum load voltage also covers the 1.8 V logic rails common in low-power MCU and FPGA designs.

The SC-70-6 package is a standard TI footprint, widely second-sourced for assembly.

Frequently asked questions

Does TPS22919DCKR have reverse current protection?

No. The TPS22919DCKR is a unidirectional high-side switch with an N-channel MOSFET and an internal body diode that conducts from output to input when the switch is off. It does not block reverse current — a load-discharge path pulls the output low when disabled, but reverse current from a higher-voltage output to a lower-voltage input is not prevented.

What is the maximum continuous current of TPS22919DCKR?

The maximum continuous output current is 1.5 A. The 89 mOhm typical on-resistance at 1.5 A produces about 200 mW of conduction loss; the SC-70-6 package can dissipate that with adequate PCB copper area, but at elevated ambient temperatures the derating curve in the datasheet should be consulted.
