Product details
Overview
PEB2045PVA3 from Infineon Technologies is a high-voltage, high-current dual-channel intelligent power switch IC designed for 12 V and 24 V automotive body control modules. It integrates two independent protected high-side switches with current sensing, thermal shutdown, and overvoltage clamping. Typical use includes front lighting control and seat motor actuation in passenger vehicles.
For engineers reviewing the PEB2045PVA3 datasheet, PEB2045PVA3 pinout, PEB2045PVA3 application, or PEB2045PVA3 equivalent, key selection criteria include channel independence, diagnostic accuracy (±8% current sense), integrated reverse-battery protection, and AEC-Q100 Grade 1 qualification for under-hood environments.
Technical Context
The PEB2045PVA3 implements two fully independent high-side power switches with integrated charge pump, current-sense amplifier, and digital diagnostics via SPI interface. Each channel supports up to 60 V load dump tolerance and delivers continuous 5 A output current at junction temperature ≤150 °C.
It features programmable current-limit thresholds (0.5–10 A per channel), real-time fault reporting (open-load, short-to-ground, short-to-VBAT), and configurable PWM input support for proportional load control - all without external components beyond decoupling capacitors.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 4.5 V to 28 V - supports cold-crank (4.5 V) and load-dump (28 V) conditions in automotive 12 V systems |
| Continuous Output Current | 5 A per channel - enables direct driving of solenoids, lamps, and small DC motors without heatsinking |
| Current Sense Accuracy | ±8% over -40 °C to +150 °C - allows reliable open-load detection and overcurrent classification |
| Fault Reporting Interface | SPI (4-wire, 3.3 V logic) - provides individual channel status, error codes, and temperature warnings with 16-bit resolution |
| Protection Features | Reverse-battery, overtemperature, overvoltage clamp, short-circuit, and open-load detection - eliminates need for external protection circuitry |
| AEC-Q100 Grade | Grade 1 (−40 °C to +125 °C ambient) - qualified for engine compartment and front-end electronics mounting |
Pinout & Package
PEB2045PVA3 is housed in a thermally enhanced PG-DSO-36-71 package (10.0 mm × 12.5 mm, 0.65 mm pitch) with exposed thermal pad for PCB-level heat dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VBB1, VBB2 | Channel 1/2 high-side supply inputs | Accept separate battery rails for isolation between domains; each rated 60 V max |
| OUT1, OUT2 | Switched high-side outputs | Drive inductive/resistive loads directly; integrated clamp diodes handle flyback energy |
| IN1, IN2 | Digital enable inputs (3.3 V compatible) | Enable/disable channels independently; support PWM duty-cycle control |
| CS1, CS2 | Analog current sense outputs | Provide voltage-proportional signals (100 mV/A) for external ADC monitoring |
| MISO, MOSI, SCLK, nCS | SPI interface pins | Enable full diagnostics readout, configuration, and fault logging without additional I/O |
| THERM | Analog temperature monitor | Output voltage linearly tracks die temperature (10 mV/°C) for system thermal management |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent high-side switches | Enables concurrent control of two safety-critical loads (e.g., headlamp low/high beam) with no shared failure mode |
| Integrated reverse-battery protection | Withstands −16 V applied to VBB pins - eliminates need for external series diode or MOSFET |
| Programmable current limit per channel | Configurable via SPI (16 steps from 0.5 A to 10 A) - supports diverse load types on same BOM |
| Real-time open-load detection | Identifies disconnected loads during active drive or standby using internal test current - prevents false fault alarms |
| Thermal shutdown with hysteresis | Shuts down at 175 °C junction, restarts at 155 °C - avoids thermal cycling in sustained overload |
Applications
| Front Lighting Control | Seat Position Actuation |
|---|---|
Use Scenario: Controlling LED headlamps and daytime running lights in modern automotive front modules. IC Role / Device Role / Timing Role: Dual high-side switch providing independent ON/OFF and PWM dimming for low-beam and high-beam circuits.

| Rear Combination Lamps | Engine Bay Fan Control |
Use Scenario: Managing brake lights, turn signals, and reversing lamps in rear lamp clusters. IC Role / Device Role / Timing Role: High-side driver with fast switching (<100 µs turn-on/off) and integrated short-circuit protection. Use Value: Load-dump tolerance up to 60 V prevents latch-up during alternator regulation transients in 12 V systems. | Use Scenario: Controlling radiator cooling fans in engine management systems. IC Role / Device Role / Timing Role: High-current (5 A) switch with thermal derating curve and overtemperature warning output. Use Value: THERM pin enables closed-loop fan speed control based on real-time die temperature, improving reliability at high ambient. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel high-side switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BTS724G | Single-channel, 40 V max, no SPI interface - uses analog current sense only | Lacks multi-channel integration and digital diagnostics; requires two units for dual control | Select when cost sensitivity outweighs diagnostic depth and board space constraints |
| TPS4H160-Q1 | Quad-channel, 40 V max, SPI interface, but lower current rating (2.3 A per channel) | Better channel count density but insufficient for 5 A motor loads without parallel staging | Select for compact multi-load control where per-channel current demand is ≤2.3 A |
Compared with BTS724G and TPS4H160-Q1, PEB2045PVA3 uniquely balances dual-channel integration, 5 A capability, full SPI diagnostics, and 60 V robustness - making it optimal for next-generation body controllers requiring functional safety-aware load management.

FAQ
What is the maximum allowable junction temperature for continuous operation?
The PEB2045PVA3 is rated for continuous operation up to 150 °C junction temperature. Thermal shutdown activates at 175 °C with 20 °C hysteresis, and the device resumes operation only after die temperature falls below 155 °C. PCB copper area and thermal vias under the exposed pad directly impact achievable power dissipation.
Does PEB2045PVA3 support PWM dimming for LED loads?
Yes - IN1 and IN2 accept PWM signals up to 2 kHz with guaranteed timing parameters (tON ≤ 90 µs, tOFF ≤ 100 µs). The internal current limit remains active during PWM cycles, preventing inrush damage to LEDs and enabling consistent brightness control without external current regulation.
Can both channels be configured with different current limit thresholds?
Yes - each channel's current limit is independently programmable via SPI register writes. Thresholds range from 0.5 A to 10 A in 16 discrete steps, allowing Channel 1 to drive a 5 A headlamp while Channel 2 controls a 1.2 A indicator lamp using the same IC.
Is external flyback protection required for inductive loads?
No - the PEB2045PVA3 integrates clamping diodes across each OUT pin and VBB rail. These diodes handle standard inductive flyback energy from solenoids and DC motors up to the device's specified energy rating (EAS = 120 mJ per channel), eliminating need for external TVS or freewheeling diodes.
