BTS722204ESPXUMA1 Overview
Background: A high-side power switch (also called a smart high-side switch, semiconductor relay, or solid-state fuse) is a power-management semiconductor that sits between the battery/load supply and the load, replacing a discrete MOSFET plus fuse plus relay combination. Programmable logic-level inputs (here, 3.3 V and 5 V compatible) turn the channels on; integrated protection handles overcurrent, overtemperature, short-circuit, reverse battery and ground-loss events. High-side switches belong to the broader hierarchy: power switch -> load driver -> power management IC -> semiconductor.
Key features of the BTS722204ESPXUMA1 include daisy-chain capable SPI for multi-device addressing, slew-rate control for electromagnetic-compatibility tuning, ReverseON operation that keeps the channels conducting during reverse polarity (low power dissipation in that mode), programmable restart after overcurrent, and absolute/dynamic temperature limitation with controlled restart. The SPI also reports open-load, short-to-ground and short-to-battery diagnostics per channel.
Architecturally, each channel is built around an N-channel vertical power MOSFET driven by a charge pump, with the SPI block handling configuration, fault flags and daisy-chain pass-through. Channels 0/1 are rated 4 A (lower RDS(on) region of about 13.5 mOhm) and channels 2/3 are rated 7 A (RDS(on) about 5.5 mOhm), giving designers flexibility to pair heavier loads (H-bridge half-bridges, pumps) with lighter loads (lamps, LEDs) on one IC.
Typical applications include body-control modules, front and rear lighting, seat-control and mirror-adjust loads, HVAC blowers, and any 12 V automotive load requiring protected switching with diagnostic feedback. Use the BTS722204ESPXUMA1 when you need per-channel current telemetry, low quiescent current in standby, and AEC-Q100-grade robustness in a small PG-TSDSO-24-32 footprint.
Design consideration: because the device is SPI-controlled, the host microcontroller must reserve one SPI peripheral and three GPIO pins (CS, SCLK, SDO); for multi-IC harnesses enable the daisy-chain mode to share one CS line. Decoupling, ground returns and thermal copper area under the exposed pad are critical for sustaining the 7 A channels.

Typical Applications
BTS722204ESPXUMA1 is suitable for 6 applications: Automotive Body Control Module (BCM), Front and Rear Automotive Lighting, HVAC Blower and Fan Drivers, Power Seat and Power Mirror Adjusters, Wiper and Washer Pump Control, Industrial 12 V / 24 V Relay Replacement.
Automotive Body Control Module (BCM)
The BTS722204ESPXUMA1 is well suited to driving mixed automotive loads in a body-control module where per-channel diagnostics and AEC-Q100 robustness are required. Its four channels - two at 4 A and two at 7 A - cover lamps, mirror adjusters, seat motors and HVAC blowers from one PG-TSDSO-24-32 IC. The integrated SPI with daisy-chain support lets the BCM microcontroller poll open-load, short-to-GND and short-to-Vbat status for each output, supporting ISO 26262 functional-safety diagnostic coverage goals. ReverseON keeps the channels conducting during reverse-battery events without dissipating full load current, and programmable restart after overcurrent lets the host choose between latch-off and auto-retry strategies.
Recommended
Front and Rear Automotive Lighting
For driving halogen, incandescent or LED front and rear lamp clusters, the BTS722204ESPXUMA1's 7 A channels at 5.5 mOhm RDS(on) deliver low conduction loss across the harness. The two lower-rated 4 A channels can run smaller lamps or LED driver stages, while the two 7 A channels can drive high-beam, low-beam or tail-lamp loads directly. Slew-rate control limits the di/dt during turn-on, reducing EMC emissions that would otherwise require additional filtering. Diagnostic feedback via SPI flags lamp-out conditions (open load) directly to the BCM without extra current-sense circuitry, lowering BOM cost and PCB area compared with discrete MOSFET solutions.
Recommended
HVAC Blower and Fan Drivers
The BTS722204ESPXUMA1's 7 A channels easily handle HVAC blowers and radiator fans used in 12 V automotive platforms. Each channel's integrated thermal shutdown and dynamic temperature limitation with controlled restart protect the device against stalled-rotor conditions without host intervention. RDS(on) of 5.5 mOhm on the 7 A channels keeps conduction losses below 0.3 W at full load, so the PG-TSDSO-24-32 exposed pad can dissipate the heat into a moderate copper pour on the PCB. Overcurrent protection with programmable restart allows the system to clear a temporary stall (such as ice in the blower) and resume operation once the fault clears, improving perceived quality versus latch-off behavior.
Recommended
Power Seat and Power Mirror Adjusters
Power-seat and power-mirror adjusters need four to six protected half-bridge outputs and per-channel current limiting - exactly what the BTS722204ESPXUMA1 family addresses. While the BTS722204ESPXUMA1 itself is a high-side switch, two devices can be combined to form four half-bridges (one high-side channel per direction), or it can be paired with companion Infineon low-side switches for full H-bridge motor control. The 4 A and 7 A channel split matches typical seat-motor current profiles, and SPI-based stall detection lets the host recognise end-of-travel and jam conditions in real time, improving safety and customer experience.
Recommended
Wiper and Washer Pump Control
Wiper motors and washer pumps benefit from the BTS722204ESPXUMA1's overcurrent and short-circuit protection. The 7 A channel handles intermittent wiper-motor inrush while the 4 A channel can drive the washer pump. ReverseON operation protects the IC and harness during jump-start or reverse-battery service events, and the daisy-chain SPI allows multiple BTS722204ESPXUMA1 devices to share one CS line in large BCMs with many loads. Programmable restart lets the system automatically retry after a stalled-wiper event, while SPI fault flags log the failure for service diagnostics.
Recommended
Industrial 12 V / 24 V Relay Replacement
Outside automotive, the BTS722204ESPXUMA1 can replace electromechanical relays in industrial 12 V systems that need solid-state reliability, silent switching, and integrated diagnostics. The 4 A/4 A/7 A/7 A channel ratings cover solenoids, small motors and indicator loads, while the SPI diagnostic interface can be driven by an industrial MCU or even an SPI-to-USB bridge for test and configuration. AEC-Q100-grade robustness gives the device wider temperature margin than typical industrial-grade parts, useful in unenclosed cabinets or outdoor enclosures where the operating temperature can exceed 85 C ambient.

Key Differentiators
- Daisy-chain SPI for multi-IC BCMs (vs Classic BTS716GP two-channel high-side switch)
- Mixed 4 A/4 A/7 A/7 A current ratings (vs BTS70402EPGXUMA1 (2-channel))
- ReverseON low-power reverse-polarity operation (vs Older BTS724L1 (no ReverseON))
Design Notes
Estimated: at Vbb=14 V, VOUT=14 V (full-on lamp) and I=7 A on the low-RDS(on) channel, dissipation is P = I^2 * RDS(on) = 7^2 * 0.0055 = 0.27 W per channel; with all four channels at full load the package dissipates around 1 W. Solder the exposed pad to at least 1 square inch of 2 oz copper to keep the junction below 150 C ambient-rated limit. If two channels run continuous 7 A simultaneously, place thermal vias under the exposed pad to the inner PCB plane and consider adding a small heat-spreader copper pour on the opposite PCB side.
Place the SPI trace impedance-matched (typically 50 ohm single-ended with a series 22-33 ohm resistor at SDO) to avoid ringing on the SDO line. The daisy-chain SDO-to-SDI link should be kept short (<50 mm) and routed away from the OUT traces to prevent capacitive coupling of high-di/dt load transients into the SPI logic. Add a 100 nF decoupling capacitor as close as possible to the Vbb pin and a bulk 10-47 uF electrolytic or polymer capacitor on the same Vbb node to absorb load-dump transients.
Do not float the CSN pin - tie it to the MCU CS GPIO so the device is not unintentionally selected on power-up and drives SDO low, blocking other devices on a shared SPI bus. Ensure the MCU drives SCLK, SDI and CSN as push-pull outputs; open-drain configuration can cause spurious clocks and latched fault states. When using daisy-chain mode, verify that the number of cascaded devices multiplied by 8 bits per device fits the host SPI peripheral's programmable data length (some MCUs cap at 16 or 32 bits); use two SPI transactions if the chain exceeds the MCU's single-transfer length.
Slew-rate control is programmable per channel via SPI on the BTS722204ESPXUMA1; for EMC-sensitive lamp loads choose the slowest slew rate that meets the application's turn-on timing requirement (typically 200-500 us rise time). Faster slew rates reduce switching loss but increase radiated EMI on the OUT traces - the SPOC +2 family datasheet's EMC reference layout shows ferrite beads and Y-capacitors that can be omitted when using the slower default slew rate.
