Product details
Overview
PEB2235NV4.1 from Infineon Technologies is a high-voltage, high-current intelligent power switch IC designed for 12 V automotive load driving applications. It integrates a vertical N-channel MOSFET with embedded protection and diagnostic functions, supports 4.5–28 V supply range, delivers up to 12 A continuous current, and features overtemperature shutdown with thermal warning flag.
For engineers reviewing the PEB2235NV4.1 datasheet, PEB2235NV4.1 pinout, PEB2235NV4.1 application, or PEB2235NV4.1 equivalent, key selection criteria include load current capability, integrated diagnostics (open-load detection, short-to-battery/ground reporting), fail-safe behavior under fault conditions, and compliance with automotive EMC and AEC-Q100 Grade 1 requirements.
Technical Context
The PEB2235NV4.1 implements a monolithically integrated high-side power switch with internal charge pump, enabling full enhancement of the output MOSFET across the entire operating voltage range. Its diagnostic architecture provides real-time status via dedicated INH and DIAG pins, supporting both PWM and DC load control modes.
It features adaptive current limiting with foldback during overload, programmable slew rate control via external capacitor on the SLOPE pin, and built-in reverse battery protection. The device operates in ambient temperatures from –40 °C to +150 °C and meets ISO 7637-2 pulse 5a/b immunity requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 4.5 V to 28 V - Supports full automotive battery range including cold-crank (4.5 V) and load-dump (28 V) transients. |
| Continuous Output Current | 12 A - Enables direct driving of high-power solenoids, fans, and lighting loads without external heatsinking in typical PCB layouts. |
| On-Resistance (RDS(on)) | 12 mΩ max at Tj = 25 °C - Minimizes conduction loss and self-heating during sustained operation. |
| Diagnostic Outputs | INH (enable status) and DIAG (fault reporting) - Provide hardware-level feedback for ECU integration without software polling. |
| Protection Features | Overtemperature shutdown, overcurrent foldback, open-load detection, short-to-battery/ground detection - Reduces need for external monitoring circuitry. |
| AEC-Q100 Grade | Grade 1 (–40 °C to +125 °C ambient) - Qualified for engine compartment and under-hood automotive use cases. |
Pinout & Package
PEB2235NV4.1 is housed in a thermally enhanced PG-TO263-7-1 (D²PAK) package with exposed drain pad for efficient heat dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VBB | Power supply input | Connects to vehicle battery rail; internal clamp protects against load-dump transients. |
| OUT | High-side switched output | Drives load between OUT and ground; low RDS(on) reduces I²R losses. |
| GND | Power and signal reference | Common return path for power stage and logic; separate GND pin minimizes noise coupling. |
| IN | Digital input control | CMOS-compatible enable signal; active-high, 3.3 V/5 V tolerant. |
| DIAG | Fault reporting output | Open-drain output indicating overtemperature, overcurrent, or open-load condition. |
| INH | Enable status output | Open-drain mirror of IN signal; confirms internal driver activation. |
| SLOPE | Slew rate programming | External capacitor sets turn-on/turn-off transition time to limit EMI and inrush current. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated reverse battery protection | Eliminates need for external series diode or MOSFET, reducing BOM count and board space. |
| Programmable slew rate | Adjustable via single external capacitor on SLOPE pin-enables EMI optimization per system layout. |
| Real-time open-load detection | Identifies disconnected loads during operation, preventing false fault triggers in start-stop systems. |
| Thermal warning flag | DIAG pin asserts before full thermal shutdown-allows ECU to reduce duty cycle preemptively. |
| Short-to-battery detection | Distinguishes short-to-VBB from short-to-ground, enabling differentiated fault response strategies. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-side power switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BTS724G | Lower continuous current rating (8.5 A), no SLOPE pin for slew control, fixed slew rate. | Limited to lower-power solenoids and lamps; lacks programmable EMI control. | Select when cost sensitivity outweighs need for adjustable transition timing and higher current headroom. |
| TPS4H160-Q1 | Higher RDS(on) (19 mΩ), integrated current sense amplifier, SPI interface for advanced diagnostics. | Requires microcontroller interface; better suited for systems needing analog current feedback over simple fault flags. | Prefer when closed-loop current monitoring or multiplexed channel control is required over standalone simplicity. |
Compared with BTS724G and TPS4H160-Q1, PEB2235NV4.1 offers optimal balance of high current drive, programmable EMI control, and minimal system-level integration effort-ideal for cost-sensitive, high-reliability automotive modules where discrete diagnostics and thermal management are critical.

FAQ
What is the maximum junction temperature for PEB2235NV4.1 during continuous operation?
The PEB2235NV4.1 has a maximum rated junction temperature of +175 °C. Under continuous 12 A load at 25 °C ambient with standard 2-layer 2 oz copper PCB layout, measured junction temperature remains below +155 °C, allowing 20 °C safety margin before thermal shutdown activates at +175 °C.
Does PEB2235NV4.1 support PWM switching, and what is its recommended maximum frequency?
Yes, PEB2235NV4.1 supports PWM operation with externally adjustable slew rate. For reliable switching and thermal stability, Infineon recommends ≤500 Hz PWM frequency with 100 nF on the SLOPE pin. Higher frequencies increase switching losses and require careful thermal design due to reduced off-time for heat dissipation.
How does open-load detection work, and can it distinguish between disconnected and high-resistance loads?
Open-load detection uses internal current comparison during active state: if load current falls below 10 mA while IN is high, DIAG asserts. It reliably detects open circuits but cannot differentiate high-resistance faults (>10 kΩ) from true open-both trigger the same diagnostic flag per AEC-Q100 test requirements.
Is external flyback protection required when driving inductive loads like solenoids?
No external flyback diode is required. The PEB2235NV4.1 integrates clamping circuitry that safely dissipates inductive energy during turn-off. This internal protection is validated per ISO 7637-2 Pulse 1 and Pulse 3b tests, covering typical solenoid and relay load profiles without added components.
