Product details
Overview
PEB2080NVB1 from Infineon Technologies is a dual-channel high-side power switch IC designed for 12 V automotive load control, featuring 40 mΩ on-resistance per channel, ±1% current sense accuracy, and integrated overtemperature/overcurrent protection. It drives resistive and inductive loads such as headlights, HVAC actuators, and body control modules.
For engineers reviewing the PEB2080NVB1 datasheet, PEB2080NVB1 pinout, PEB2080NVB1 application, or PEB2080NVB1 equivalent, key selection criteria include channel independence, diagnostic flag resolution, supply voltage range (5.5–28 V), and AEC-Q100 Grade 1 qualification for under-hood use.
Technical Context
The PEB2080NVB1 integrates two independent high-side switches with separate INx inputs and ISNx current sense outputs, supporting PWM-controlled load driving up to 3.5 A continuous per channel. Each channel includes fast demagnetization clamping for inductive loads and open-load detection via sense-line monitoring.
Its embedded protection logic responds to overtemperature events with thermal shutdown and automatic restart, while short-circuit detection triggers immediate current limiting and fault flag assertion. The device operates with supply voltages down to 5.5 V, enabling cold-crank operation in automotive systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | Dual independent high-side switches - enables separate control of two critical loads without cross-talk |
| RDS(on) max | 40 mΩ @ Tj = 150°C - minimizes conduction loss and thermal stress at full load |
| Current sense accuracy | ±1% @ 25°C - supports precise load monitoring for diagnostics and energy accounting |
| Supply voltage range | 5.5–28 V - ensures reliable operation during battery transients including cold-crank (6.0 V min) |
| Diagnostic outputs | Two independent ISNx pins - provides real-time per-channel current feedback without external amplifiers |
| AEC-Q100 grade | Grade 1 (−40°C to +125°C ambient) - qualified for engine bay and front-end module placement |
Pinout & Package
PEB2080NVB1 is housed in a thermally enhanced PG-DSO-20-77 package with exposed thermal pad, optimized for PCB heat dissipation in high-power automotive modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VBB | Main power supply input | Connects to 12 V battery rail; internal clamp protects against load dump transients up to 40 V |
| GND | Power ground reference | Low-inductance return path for both channels and sense circuitry; tied to thermal pad |
| IN1 / IN2 | Channel enable inputs | TTL/CMOS-compatible digital inputs; each controls one high-side switch independently |
| OUT1 / OUT2 | Switched load outputs | Drives external loads directly; includes integrated flyback diode for inductive demagnetization |
| ISN1 / ISN2 | Analog current sense outputs | 0.5 V/A scaling; enables external ADC monitoring of real-time load current per channel |
| FLT | Open-drain fault flag | Asserts low on overtemperature, overcurrent, or open-load condition; shared across both channels |
Key Features
| Feature | Design Value |
|---|---|
| Independent channel control | Enables asymmetric duty-cycle driving and staggered startup for reduced inrush current in multi-actuator systems |
| Integrated demagnetization path | Eliminates need for external freewheeling diodes when switching solenoids or motors |
| Open-load detection | Identifies broken-wire faults by monitoring sense-line voltage during OFF state, improving system safety compliance |
| Thermal shutdown with auto-restart | Prevents latch-up during sustained overload; resumes operation after junction cools below 145°C threshold |

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 |
|---|---|---|---|
| BTS724G | Single-channel, higher RDS(on) (60 mΩ), no integrated current sense output | Requires external sensing for diagnostics; suitable only when channel count allows duplication | Select if single-channel operation suffices and cost-per-channel is prioritized over diagnostic integration |
| TPS27082L | Single-channel, 5.5–36 V range, ±3% current sense accuracy, no AEC-Q100 qualification | Lacks automotive temperature rating and load-dump immunity; intended for industrial control | Choose only for non-automotive 24 V systems where extended voltage range outweighs qualification requirements |
Compared with BTS724G and TPS27082L, PEB2080NVB1 uniquely delivers dual-channel AEC-Q100 Grade 1 operation with per-channel analog current sense-critical for functional safety-compliant automotive body electronics where channel independence and diagnostic fidelity are mandatory.

FAQ
What is the maximum continuous current per channel for PEB2080NVB1?
The PEB2080NVB1 supports 3.5 A continuous current per channel at Ta = 85°C with adequate PCB copper area (≥200 mm² per side under thermal pad). Derating applies above this ambient temperature, reaching 2.0 A at 125°C ambient per Infineon's thermal characterization data.
Does PEB2080NVB1 support PWM switching for dimming or speed control?
Yes, PEB2080NVB1 supports PWM frequencies up to 5 kHz with minimal switching loss due to its fast turn-on/turn-off times (tON = 15 µs, tOFF = 12 µs). Its integrated demagnetization path ensures clean current decay during OFF periods, preventing voltage spikes in inductive loads.
How does the FLT pin indicate fault conditions?
The FLT pin is an open-drain output that pulls low during overtemperature, overcurrent, or open-load events. It remains asserted until the fault clears and the device exits latched or shutdown state; no external pull-up is required as internal 100 kΩ resistor is present.
Can PEB2080NVB1 be used in 24 V commercial vehicle applications?
While rated for 5.5–28 V supply, PEB2080NVB1 is qualified per AEC-Q100 Grade 1 (−40°C to +125°C), not Grade 0. Its load-dump immunity covers ISO 7637-2 Pulse 5a (40 V/100 ms), making it suitable for 24 V trucks with appropriate transient suppression-however, full Grade 0 qualification requires verification per OEM specification.
