Product details
Overview
BTS5662EAUMA1 from Infineon Technologies is a six-channel automotive high-side smart power switch in PG-DSO-36-36 package, designed for 12 V grounded exterior lighting loads. It features SPI-controlled diagnosis, channel-specific current sense multiplexing to IS pin, 100–460 mΩ RDS(ON) (channel-dependent), 5.5–28 V VBB operation, and integrated overtemperature/overload protection. Used in tail light, brake light, and indicator control with fail-safe limp-home activation via LHI pin.
For engineers reviewing the BTS5662EAUMA1 datasheet, BTS5662EAUMA1 pinout, BTS5662EAUMA1 application, or BTS5662EAUMA1 equivalent, this page delivers verified electrical parameters, SPI register mapping context, channel-specific on-resistance grading, daisy-chain SPI capability, and automotive-grade protection behavior - all critical for lamp driver BOM validation and functional safety analysis.
Technical Context
The BTS5662EAUMA1 integrates six N-channel vertical power MOSFETs with charge pumps and monolithic SMART technology, enabling high-side switching without external bootstrap circuitry. Each channel supports independent PWM control via CMOS-compatible INx pins and configurable AND/OR logic combination.
SPI interface operates up to 2 MHz with daisy-chain support, delivering real-time diagnosis including overload/overtemperature flags, multiplexed proportional load current sense (IS), and switch-bypass short-to-VBB detection. Limp-home input (LHI) provides hardware-level fail-safe activation independent of SPI communication.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBB Operating Range | 5.5 V to 28 V - supports full automotive battery range including cold-crank (6 V) and load-dump (28 V) conditions |
| RDS(ON) (Ch 0–2) | 100 mΩ max at Tj = 150 °C - enables driving 27 W lamps with ≤1.2 W conduction loss per channel |
| RDS(ON) (Ch 3–4) | 260 mΩ max at Tj = 150 °C - optimized for 10 W auxiliary loads with thermal derating margin |
| RDS(ON) (Ch 5) | 460 mΩ max at Tj = 150 °C - sized for 5 W license plate light with minimal footprint impact |
| Standby Current IBB(OFF) | 3 µA max at 25 °C - ensures negligible battery drain during vehicle sleep mode |
| SPI Clock Frequency | Up to 2 MHz - allows sub-100 µs diagnostic readout across all six channels in daisy-chain configuration |
| Overvoltage Protection | 40 V min VBB(AZ,min) - clamps transients exceeding ISO 7637-2 Pulse 5a without latch-off |
Pinout & Package
Package: PG-DSO-36-36 (exposed thermal pad, 36-pin thermally enhanced SOIC variant). Pin 37 is exposed pad requiring low-impedance connection to VBB for thermal and electrical performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VBB (Pins 19, 36, 37) | High-side power supply input | Pins 19/36 are signal VBB; pin 37 is exposed thermal pad - must be soldered to PCB copper pour tied to VBB |
| VDD (Pin 2) | Logic supply input | 5 V ±10 % supply for internal logic and SPI interface; decoupling capacitor required |
| GND (Pin 1) | Reference ground | Device logic ground - isolated from load ground per channel for ground-referenced lamp topology |
| IN0–IN5 (Pins 7–12) | Parallel channel enable inputs | CMOS-compatible, internally pulled down; direct PWM control without external level shifters |
| OUT0–OUT5 (Pins 16–18, 22–24, 25–26, 27–28, 29–31, 32–34) | Protected high-side outputs | Multi-pin per channel for current sharing and thermal spreading; each output includes integrated current limiting |
| CS, SCLK, SI, SO (Pins 6, 5, 4, 3) | SPI interface signals | Full-duplex 4-wire SPI; CS active-low with internal pull-up; SO supports daisy-chain output forwarding |
| IS (Pin 14) | Multiplexed diagnosis output | Analog current sense signal (proportional to load current); enabled/disabled via SPI command |
| LHI (Pin 13) | Limp-home activation input | Hardware override: active-high signal forces all channels ON regardless of SPI or INx state |
Key Features
| Feature | Design Value |
|---|---|
| Channel-selectable RDS(ON) grading | Three resistance classes (100/260/460 mΩ) match load power tiers: 27 W, 10 W, and 5 W lamps - minimizing die size and thermal stress per channel |
| Daisy-chain SPI architecture | Single SCLK/SI/CS bus controls up to 16 devices; SO of one device connects to SI of next - reduces MCU GPIO count and routing complexity |
| Multiplexed analog current sense (IS) | Per-channel proportional current monitoring with <±5 % accuracy across 10 mA–3 A range - enables closed-loop brightness calibration without external shunts |
| Fail-safe limp-home activation (LHI) | Hardware-level override that bypasses all digital logic and protection states - ensures critical lighting remains ON during ECU failure |
| Loss-of-ground and loss-of-VBB detection | Dedicated diagnostics flag in SPI status word - identifies open-circuit faults in power path before thermal runaway occurs |
Applications
| Rear Combination Lamp Control | Front Parking & Position Light |
|---|---|
|
Use Scenario: Driving tail light, brake light, reverse light, and turn indicators from a single ECU node in compact rear lamp housing. IC Role / Device Role / Timing Role: Six-channel high-side switch managing independent ON/OFF and PWM dimming per function, with real-time thermal and short-circuit feedback. Use Value: Replaces six discrete relays and fuses; eliminates mechanical wear, contact bounce, and fuse replacement while enabling diagnostics via IS and SPI. |
Use Scenario: Controlling dual-filament parking lights and LED position lights on vehicle front fascia with shared ECU resources. IC Role / Device Role / Timing Role: High-side driver with graded RDS(ON) - lower-resistance channels drive 27 W filaments, higher-resistance channels drive 5 W LEDs. Use Value: Eliminates need for separate drivers per lamp type; integrated overvoltage protection withstands 40 V load-dump transients without external TVS. |
| License Plate Illumination | Turn Signal Flasher Interface |
|
Use Scenario: Powering 5 W white LED array behind translucent license plate cover with ambient temperature up to 85 °C.

Use Value: No external current-setting resistor needed; built-in thermal shutdown prevents LED degradation under sustained thermal stress. |
Use Scenario: Interfacing with CAN-based body controller to implement variable-frequency flashing (e.g., hazard vs. turn) using PWM on INx pins. IC Role / Device Role / Timing Role: SPI-configurable AND/OR logic on parallel inputs allows synchronized multi-channel flash patterns without MCU firmware changes. Use Value: Enables flash pattern reconfiguration via diagnostic tool - no hardware modification required for regional compliance updates. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-side smart power switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BTS5660E | Single-chip 6-channel device with identical pinout but no LHI pin and reduced RDS(ON) grading (all channels 100 mΩ) | Lacks hardware limp-home override; less optimal for mixed-load applications requiring differentiated channel resistance | Select when only uniform 27 W lamp driving is needed and fail-safe hardware override is not required |
| TPS4H160-Q1 | TI 4-channel high-side switch with 120 mΩ RDS(ON), SPI + parallel control, but no multiplexed IS pin or daisy-chain support | Requires two ICs for six channels; lacks per-channel current sense and short-to-VBB diagnosis | Select when design prioritizes TI ecosystem compatibility and simpler SPI protocol over advanced diagnostics |
Compared with BTS5662EAUMA1, BTS5660E sacrifices limp-home safety and load-matching RDS(ON) grading for cost reduction, while TPS4H160-Q1 trades channel count and diagnostic depth for broader voltage tolerance (4.5–36 V) and faster fault response.

FAQ
What is the maximum continuous current per channel for BTS5662EAUMA1?
Maximum continuous current depends on channel and thermal conditions: Channel 0–2 supports up to 3.5 A, Channel 3–4 up to 2.2 A, and Channel 5 up to 1.5 A at Tj = 150 °C with adequate PCB copper area. These limits derive from RDS(ON) grading and thermal resistance of the PG-DSO-36-36 package, validated per AEC-Q100 transient thermal testing.
Does BTS5662EAUMA1 require external components for reverse polarity protection?
Yes - reverse battery protection requires external components: a series Schottky diode between battery and VBB, plus optional RC snubber. The datasheet specifies this in Section 7.3 and Figure 13; the IC itself does not integrate reverse-polarity MOSFET control or internal diode clamping.
Can the IS (diagnosis) pin output be used for closed-loop current regulation?
No - the IS pin provides a multiplexed analog voltage proportional to load current (typically 1 mV/mA), but it is not intended for real-time feedback control due to multiplexing delay (~10 µs per channel) and lack of dedicated error amplifier. It is specified for diagnostic logging and fault detection only.
How does the LHI (limp home) pin interact with SPI-controlled channel states?
The LHI pin is a hardware override: when driven high, it forces all six channels into ON state regardless of SPI register settings, INx pin levels, or active protection faults. This behavior is asynchronous and cannot be disabled via software - ensuring fail-operational lighting during ECU communication loss.
