100 mA high-side switch — load budget and protection
The TPS22945DCKR is a single-channel, high-side P-channel load switch from Texas Instruments, rated for 100 mA continuous output. The Auto Restart feature means the switch re-tries after a fault clears, useful for capacitive loads or transient overcurrent events where a latched-off part would require a power cycle.
Temperature range and package — where it fits
The SC-70-5 (SOT-353) package occupies roughly 2 mm × 2 mm on the board — a fit for space-constrained designs like sensor modules or portable instruments.
