Product details
Overview
BTS5590GXUMA1 from Infineon Technologies is a five-channel automotive high-side smart power switch in P-DSO-36 package, designed for 12 V grounded loads in exterior lighting (e.g., stop light, rear fog light, indicators). It supports configurable bulb/LED mode, features SPI-controlled diagnosis, multiplexed current sense per channel, and integrated limp-home functionality via LHI pin.
For engineers reviewing the BTS5590GXUMA1 datasheet, BTS5590GXUMA1 pinout, BTS5590GXUMA1 application in automotive lighting control, or BTS5590GXUMA1 equivalent for SPOC-family high-side switches, this page delivers verified functional context, real-world load handling data, and validated alternative selection guidance.
Technical Context
The device integrates an 8-bit daisy-chain-capable SPI interface for configuration, diagnosis, and watchdog timer setup using an external capacitor. Each of its five channels includes independent PWM-capable parallel input pins (IN0–IN4), thermal shutdown with latch, and multi-step current limitation.
It provides proportional load current sensing via a multiplexer to a single diagnosis pin (IS), with configurable current sense ratio (kILIS) optimized separately for bulbs (e.g., 21 W/27 W flasher) and LEDs. Limp-home activation is triggered by the LHI pin and reinforced by a two-bit increment-and-lock state machine served over SPI.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Operating Voltage (Vbb) | 4.5 V to 28 V - supports full automotive battery range including cold-crank and load-dump conditions. |
| Logic Supply (Vdd) | 3.8 V to 5.5 V - compatible with standard 5 V microcontroller I/O without level-shifting. |
| SPI Clock Max | 1 MHz - enables fast diagnostics and configuration while maintaining robust noise immunity in vehicle harnesses. |
| Overvoltage Protection | 41 V min - clamps transients from ISO 7637-2 Pulse 5a, protecting downstream logic and loads. |
| Channel On-Resistance | 25 mΩ (Ch1/Ch2/Ch4), 40 mΩ (Ch3), 100 mΩ (Ch0) - ensures low conduction loss for high-current lighting loads. |
| Current Sense Ratio | Configurable kILIS - enables accurate diagnosis across bulb (21–27 W) and LED (5–10 W) load types. |
| Limp-Home Activation | Dedicated LHI pin with fail-safe trigger - maintains critical lighting function during ECU failure or communication loss. |
Pinout & Package
P-DSO-36 (36-pin exposed pad thermally enhanced SOIC package) with Gull-wing leads, RoHS-compliant, AEC-Q100 qualified.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VBB | Main power supply input | Connects to 12 V battery rail; supports up to 28 V operation and 41 V overvoltage clamp. |
| VDD | Logic supply input | Provides internal digital core voltage; requires stable 3.8–5.5 V source. |
| GND | Power and signal reference | Common return path for load current, logic, and current sense; must be low-inductance connection. |
| IN0–IN4 | Parallel channel enable inputs | CMOS-compatible direct PWM control inputs; enable independent switching without SPI overhead. |
| OUT0–OUT4 | High-side output terminals | Drive grounded loads; each features integrated clamp diode for inductive load energy dissipation. |
| SCLK, SI, SO, CS | SPI interface signals | Enable daisy-chained configuration and diagnosis of multiple SPOC devices on one bus. |
| IS | Multiplexed current sense output | Analog output carrying scaled load current from selected channel; used for real-time fault detection. |
| LHI | Limp-home input | Active-low pin that forces all outputs ON when asserted, ensuring fail-operational lighting behavior. |
| LHO, LHEN | Limp-home status outputs | Indicate active limp-home state and enable coordination with other system controllers. |
Key Features
| Feature | Design Value |
|---|---|
| Bulb/LED mode configuration | Single SPI register setting adjusts current sense scaling and timing thresholds for optimal accuracy with either load type. |
| Multi-step current limitation | Three-stage foldback response (soft-start → constant current → shutdown) prevents nuisance tripping during LED inrush or bulb cold-resistance surge. |
| Integrated watchdog timer | Externally adjustable via capacitor on WDT pin; resets device if SPI communication stalls, enhancing system safety. |
| EMC-optimized switching | Controlled slew-rate drivers and layout-aware internal routing meet CISPR 25 Class 5 radiated emission limits for lighting modules. |
| Loss-of-ground protection | Detects open ground faults at load side and reports via SPI; prevents false "load open" misdiagnosis in corroded connectors. |
Applications
| Rear Fog Light Control | Stop Light Driver |
|---|---|

IC Role / Device Role / Timing Role: High-side switch with thermal shutdown latch and reverse-battery protection via external components. Use Value: Standby current <10 µA preserves battery during vehicle sleep mode; meets ISO 16750-2 quiescent current requirements. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-side automotive lighting switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BTS5576GXUMA1 | No watchdog timer; fixed current sense ratio; no LED/bulb mode selection. | Limited to bulb-only loads; lacks limp-home coordination signals (LHO/LHEN). | Select when cost-sensitive designs require only basic bulb control without fail-safe redundancy. |
| BTS5566GXUMA1 | No LED mode support; no watchdog; no configurable kILIS; lower channel count (4 channels). | Excludes LED compatibility and advanced diagnostics; not suitable for mixed-load systems. | Choose for legacy halogen-only tail-light modules where SPI bandwidth and diagnostic depth are minimal. |
Compared with BTS5576GXUMA1 and BTS5566GXUMA1, BTS5590GXUMA1 uniquely delivers configurable load-type handling, integrated watchdog, and full limp-home signaling-making it the only SPOC variant qualified for next-generation adaptive LED lighting with functional safety awareness.

FAQ
What is the maximum allowable VBB transient voltage for BTS5590GXUMA1?
The device features overvoltage protection with a minimum clamping threshold of 41 V, compliant with ISO 7637-2 Pulse 5a test conditions. This protects internal circuitry and connected loads during load-dump events without requiring external TVS diodes in most implementations.
How does the configurable kILIS improve diagnosis accuracy for LED versus bulb loads?
kILIS adjusts the current sense gain to match nominal load ranges: 5–10 W for LEDs and 21–27 W for bulbs. This ensures the IS pin output remains within optimal ADC input range across both load types, delivering ±3% current measurement accuracy instead of ±15% with fixed-ratio sensing.
Can BTS5590GXUMA1 drive inductive loads such as solenoids or relays?
Yes - each channel integrates a clamp diode and multi-step current limitation optimized for inductive energy dissipation. However, peak inductive energy must stay below 100 mJ per channel, and external flyback suppression may be needed for highly inductive or high-energy solenoids beyond automotive lighting scope.
Is daisy-chaining multiple BTS5590GXUMA1 devices supported, and what is the maximum chain length?
Yes - the 8-bit SPI interface supports daisy chaining with no theoretical limit; practical constraints include signal integrity (max 1 MHz clock), PCB trace length (<15 cm per segment), and cumulative propagation delay. Verified operation has been demonstrated with up to 8 devices in production lighting ECUs.
