TPS27S100ARRKR

TPS27S100ARRKR is Texas Instruments’ high-side smart switch for automotive power distribution. It integrates a load switch with protection features to simplify driving inductive loads (motors, pumps, relays) from a vehicle electrical system.
Key features:
- High-side switch with built-in current limit and short-circuit protection
- Reverse-battery protection, undervoltage lockout, and thermal shutdown
- Enable/control input and a status/flag output for fault indication
- Designed for rugged automotive environments with protection against transients
Package note:
- ARRKR denotes TI’s exact package and reel/tape format for automated assembly.
Why use it:
- Reduces external components, improves system safety, and provides fault reporting for reliable power switching in automotive ECUs and industrial controls.
For precise electrical characteristics (current limit value, input range, sleep/propagation delays, UVLO thresholds), consult the TPS27S100 datasheet and packaging documents.

Here are the typical features of the TPS27S100ARRKR (automotive Smart High-Side Switch):
- Single-channel smart high-side switch for automotive loads
- Wide input voltage range and load-dump tolerance suitable for automotive use
- Integrated protections: reverse polarity, short-to-ground, overcurrent (current limit), overvoltage, undervoltage lockout, and thermal shutdown
- Enable control input to turn the switch on/off
- Adjustable/current-limit and current-limited startup to limit inrush
- Fault diagnostic output (open-drain or similar) for status indication
- Fault latching with auto-retry behavior for protection
- Slew-rate control to minimize inrush and EMI
- Low quiescent current in the off state (efficient sleep)
- Robust, automotive-grade device with extended temperature range and RoHS compliant packaging
- Compact packaging suitable for tight automotive harness layouts
Note: exact electrical ratings (voltage range, current limit value, pinout) are specific to the device variant; verify in the datasheet for TPS27S100ARRKR.
