Typical Applications
TPS22997QRYZRQ1 is suitable for 6 applications: ADAS Processor Power Sequencing, Infotainment Display and Audio Rail Gating, FPGA and MCU Core Rail Switching, Automotive Camera and Sensor Module Power, Body Electronics and Gateway Rail Control, E-Compressor and Motor Drive Auxiliary Rails.
ADAS Processor Power Sequencing
The TPS22997QRYZRQ1 gates the core and I/O rails of ADAS SoCs such as TDA4 processors, where its 10A capacity and 4 mΞ© RON handle multi-amp core supplies with minimal drop (40 mV at 10A). The power-good output lets a sequencer or MCU confirm rail validity before releasing the next rail, while adjustable slew rate prevents inrush from collapsing upstream 5V rails during turn-on. Placed between the point-of-load converter and the processor, it adds no switching noise and only 0.4W conduction loss at full load. AEC-Q100 qualification makes it compliant for production automotive ADAS platforms.

Infotainment Display and Audio Rail Gating
Automotive infotainment head units use the TPS22997QRYZRQ1 to switch display panels and audio amplifier rails, enabling standby power savings. With a 0.1V minimum input and low-voltage GPIO-compatible ON pin, it can be driven directly from an SoC to isolate the 5V display rail. The adjustable quick output discharge actively pulls the display rail low when disabled, preventing ghosting or floating-panel conditions. Its 4 mΞ© RON keeps dissipation negligible even for multi-amp amplifier supply rails, and thermal shutdown adds a layer of protection if the display connector shorts.
Recommended
FPGA and MCU Core Rail Switching
FPGAs and MCUs often require controlled power-down to guarantee deterministic reset. The TPS22997QRYZRQ1 provides controlled turn-off of core rails with active QOD discharge, ensuring the device resets cleanly across power cycles. At currents up to 10A, its 4 mΞ© switch adds only milliohm-level IR drop, preserving the tight core voltage margin of modern FPGAs. The CT pin slew-rate control lets designers soften turn-on into large decoupling networks without external FETs or driver circuitry. This saves board area versus discrete MOSFET solutions in dense compute modules.
Recommended
Automotive Camera and Sensor Module Power
Surround-view and radar sensor modules are powered through long harnesses where inrush must be limited. The TPS22997QRYZRQ1 soft-starts the sensor rail via its CT-configured rise time, limiting inrush into camera module bulk capacitance and protecting the upstream supply from droop below reset thresholds. Its power-good flag reports rail status to the domain controller. AEC-Q100 qualification covers the harsh ambient range of automotive exterior modules, and the tiny 1.5 mm x 2 mm WQFN-HR package fits inside compact camera housings with strict board-area limits.
Recommended
Body Electronics and Gateway Rail Control
Body control modules and automotive Ethernet gateways use the TPS22997QRYZRQ1 to switch peripheral rails for transceivers and I/O expanders, enabling sleep-mode power reduction. Low power consumption when enabled and clean isolation when disabled reduce quiescent draw below module sleep budgets. The ON pin accepts low-voltage GPIO directly from a TMS320F280015x-class MCU without level shifting when bias is 3.3V. Thermal shutdown protects against connector faults, and the 10A rating covers high-current peripheral rails with ample margin.
Recommended
E-Compressor and Motor Drive Auxiliary Rails
Motor-drive systems built around gate drivers such as the DRV8353S use the TPS22997QRYZRQ1 to gate isolated auxiliary supply rails for sensors and communication circuits. During fault conditions, the load switch isolates the auxiliary domain quickly, and the QOD discharge guarantees a known state before restart. The 0.1V-5.5V input range accommodates rectified or low-voltage auxiliary rails, and 4 mΞ© RON limits heating in thermally constrained drive enclosures. Functional isolation of measurement chains (for example, TMCS1101 current sensors) becomes manageable with one small-SMD switch.

Key Differentiators
- Automotive AEC-Q100 qualification (vs TPS22997RYZR)
- Extremely low 4 mΞ© on-resistance at 10A (vs ET3164)
- Adjustable slew rate plus adjustable QOD (vs TPS22997RYZR)
Design Notes
Size the CT capacitor so the output rise time limits inrush current to a value the upstream regulator can source. Inrush approximates I = (CLOAD x VOUT) / tRISE. For a 1000 uF load charged to 5V in 2 ms, inrush is about 2.5A. Verify the bias rail is established before asserting ON, since the control circuitry is powered from VBIAS, not VIN.
At 10A and 4 mΞ© RON, conduction loss is roughly 0.4W (I2R). The 1.5 mm x 2 mm WQFN-HR package relies heavily on the PCB thermal pad; use a solid via array from the exposed pad to at least one internal ground plane. Transient overloads are handled by thermal shutdown, but do not rely on it for repeated faults - it degrades long-term reliability.
Route VIN and VOUT with wide, short copper pours rated for 10A - use at least 2 oz copper or parallel planes for the power path. Place the CT and QOD resistors/capacitors close to their pins to keep control nodes quiet. Keep the PGOOD pull-up on a clean rail, and do not float ON; drive it from a defined logic level to prevent unintended turn-on during startup.
