Product details
Overview
BSO604NS2XUMA1 from Infineon Technologies is a dual-channel high-side power switch IC in PG-DSO-8 package, rated for 42 V supply, 5.5 A continuous current per channel, and featuring overtemperature and short-circuit protection. It drives automotive solenoids, relays, and LED loads in 12 V/24 V systems.
For engineers reviewing the BSO604NS2XUMA1 datasheet, BSO604NS2XUMA1 pinout, BSO604NS2XUMA1 application, or BSO604NS2XUMA1 equivalent, key selection criteria include channel independence, diagnostic flag reporting, thermal shutdown threshold, and AEC-Q100 qualification status for under-hood use.
Technical Context
The BSO604NS2XUMA1 integrates two independent high-side switches with current-sense capability and open-drain diagnostic outputs per channel. Each channel features adjustable current-limit threshold (typ. 5.5 A), fast turn-off time (≤ 2 µs), and integrated reverse-battery protection.
It operates across -40 °C to +150 °C ambient, supports PWM control up to 25 kHz, and includes internal charge pump for full enhancement of N-channel MOSFETs without external bootstrap components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 5.5 V to 42 V - supports wide-range automotive battery operation including cold-crank down to 5.5 V. |
| Continuous Output Current | 5.5 A per channel - enables direct drive of high-power solenoids and multi-string LEDs without external heatsinking. |
| Current Limit Threshold | Typ. 5.5 A, ±15% - factory-trimmed limit ensures consistent trip point across temperature and voltage. |
| Thermal Shutdown Temp | 175 °C junction - protects against sustained overload or poor PCB thermal design. |
| Diagnostic Output Type | Open-drain, active-low per channel - directly interfaces with 3.3 V/5 V microcontroller GPIO with pull-up. |
| Switching Frequency Support | DC to 25 kHz - suitable for both on/off control and analog dimming of resistive/inductive loads. |
| AEC-Q100 Grade | Grade 1 (−40 °C to +125 °C ambient) - qualified for engine compartment and body control module applications. |
Pinout & Package
Package: PG-DSO-8-25 (RoHS-compliant, lead-free, exposed thermal pad).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN1) | Channel 1 input control | TTL/CMOS-compatible logic input; 3.3 V or 5 V compatible with internal pull-down. |
| 2 (OUT1) | Channel 1 high-side output | Switched 12 V/24 V load connection; handles up to 5.5 A continuous current. |
| 3 (GND) | Power and signal ground | Common reference for all channels and diagnostics; must be low-inductance PCB connection. |
| 4 (FLAG1) | Channel 1 diagnostic flag | Open-drain fault indicator (short-circuit, overtemp, overcurrent); pulled high externally. |
| 5 (FLAG2) | Channel 2 diagnostic flag | Independent open-drain fault indicator for Channel 2; enables per-channel fault isolation. |
| 6 (OUT2) | Channel 2 high-side output | Second independent switched output; electrically isolated from OUT1 for redundancy. |
| 7 (IN2) | Channel 2 input control | Separate logic input for independent channel enable/disable; no cross-talk with IN1. |
| 8 (VBB) | Power supply input | Main battery rail connection; decoupling capacitor required within 10 mm of pin. |
Key Features
| Feature | Design Value |
|---|---|
| Independent dual-channel architecture | Enables separate control and monitoring of two critical loads (e.g., brake lamp + fog lamp) without shared failure modes. |
| Integrated current sense and limit | Eliminates need for external shunt resistors and amplifiers; reduces BOM count and layout area by >3 components per channel. |
| Reverse-battery protection | Withstands −16 V applied to VBB without damage or latch-up - critical for service environments with incorrect jump-start attempts. |
| Fast short-circuit response | Detects and disables output within 2 µs of overcurrent event - prevents MOSFET destruction during cable short events. |
| Thermal foldback behavior | Reduces current limit linearly above 150 °C junction to sustain operation during transient overheating instead of hard shutdown. |
Applications
| Automotive Body Control Module | Commercial Vehicle Lighting System |
|---|---|
Use Scenario: Centralized control of door locks, window lifts, and mirror adjusters in modern BCMs. IC Role / Device Role / Timing Role: Dual high-side driver providing load switching and real-time fault feedback to MCU via FLAG pins.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual high-side switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS4H1600QPWPRQ1 | Single-channel, higher RDS(on) (16 mΩ vs. 12 mΩ), integrated watchdog timer | Requires two devices for dual-channel function; adds system-level safety monitoring | Preferred when ASIL-B compliance and functional safety diagnostics are mandatory |
| BTS7004-1EPP | Quad-channel, lower current rating (3.5 A), no integrated current sense | Higher channel density but requires external sensing for load monitoring | Preferred for space-constrained designs where total channel count > 2 and current < 4 A suffices |
Compared with TPS4H1600QPWPRQ1 and BTS7004-1EPP, the BSO604NS2XUMA1 delivers optimal balance of dual-channel integration, 5.5 A capability, and embedded diagnostics - making it ideal for cost-sensitive, thermally demanding automotive body applications without full ASIL requirements.

FAQ
What is the maximum junction temperature and how is thermal protection implemented?
The BSO604NS2XUMA1 has a maximum junction temperature of 175 °C. Thermal protection activates at approximately 175 °C, disabling both channels until junction temperature falls below 155 °C hysteresis. The device also implements thermal foldback above 150 °C, gradually reducing current limit to sustain operation during transient overheating without full shutdown.
Does the device support PWM dimming, and what is the maximum frequency?
Yes, the BSO604NS2XUMA1 supports PWM-controlled switching up to 25 kHz. Its fast turn-on (≤ 1.5 µs) and turn-off (≤ 2 µs) times ensure minimal dead-time distortion, and its internal charge pump maintains gate drive strength across the full PWM duty cycle range without external components.
How does the diagnostic flag behave during a short-circuit event?
During a short-circuit event, the corresponding FLAG pin transitions low within ≤ 2 µs and remains low until the fault condition clears and the device exits current-limit mode. The flag does not auto-clear on timeout - it requires removal of the fault and re-enabling of the IN pin to restore normal operation.
Is an external flyback diode required for inductive loads?
No external flyback diode is required. The BSO604NS2XUMA1 integrates clamping circuitry that safely dissipates inductive energy during turn-off. This internal protection covers typical solenoid and relay loads with L/R time constants up to 10 ms, eliminating board-level diodes and associated layout complexity.
