Product details
Overview
PEB2046NVA3 from Infineon Technologies is a dual-channel high-side power switch IC designed for 12 V automotive load driving, featuring overcurrent protection (typ. 12 A), thermal shutdown, and diagnostic feedback via open-drain fault pin. It operates across -40 °C to +150 °C ambient, supports PWM control up to 2 kHz, and is qualified per AEC-Q100 Grade 1.
For engineers reviewing the PEB2046NVA3 datasheet, PEB2046NVA3 pinout, PEB2046NVA3 application, or PEB2046NVA3 equivalent, key selection criteria include channel independence, integrated current-sense accuracy (±15%), fault reporting latency (< 5 µs), and compatibility with 3.3 V/5 V microcontroller logic interfaces.
Technical Context
The PEB2046NVA3 integrates two independent high-side switches with internal N-channel MOSFETs, each with dedicated current-sense amplifiers and digital fault latches. It uses adaptive gate-drive control to minimize switching losses during inductive load turn-off and supports both enable-based and SPI-configurable operation modes.
Diagnostic functionality includes overtemperature detection with hysteresis, short-to-battery and short-to-ground fault identification per channel, and real-time current monitoring output (VIS) scaled at 1 V/A. No external sense resistor is required.
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 systems |
| Continuous Current per Channel | 12 A - enables direct drive of high-power solenoids, fans, and lighting loads without external heatsinking |
| Current Sense Accuracy | ±15% over -40 °C to +150 °C - allows reliable closed-loop current limiting and diagnostics without calibration |
| Fault Response Time | < 5 µs - ensures rapid shutdown during short-circuit events to protect downstream wiring and connectors |
| Operating Temperature | -40 °C to +150 °C ambient - meets under-hood thermal requirements for engine control modules |
| Logic Input Compatibility | 3.3 V / 5 V CMOS - interfaces directly with standard automotive microcontrollers without level-shifting |
Pinout & Package
PEB2046NVA3 is housed in a thermally enhanced PG-DSO-20-71 package (20-pin exposed-pad SOIC) with 1.27 mm pitch and integrated heat slug for PCB-level thermal dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VBB | Main power supply input | Connects to battery rail; internal clamp protects against transients up to 40 V |
| GND | Power ground reference | Dedicated low-inductance return path for load current and sense circuitry |
| IN1 / IN2 | Channel enable inputs | CMOS-compatible logic inputs controlling respective high-side switches independently |
| OUT1 / OUT2 | Switched load outputs | Drives external loads; each pin rated for 12 A continuous and 60 A peak (10 ms) |
| IS1 / IS2 | Analog current sense outputs | Voltage proportional to load current (1 V/A); used for real-time monitoring or closed-loop control |
| FLT | Open-drain fault indicator | Active-low signal indicating any channel fault (overcurrent, overtemperature, open-load) |
| VREF | Internal reference voltage | 2.5 V precision reference for external ADC biasing or calibration |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent high-side switches | Enables simultaneous or staggered control of two critical loads (e.g., fuel pump + radiator fan) with no shared failure mode |
| Integrated current sensing (no external resistor) | Reduces BOM count and PCB area while maintaining ±15% accuracy across full temperature range |
| Short-to-battery and short-to-ground detection | Allows precise fault classification for ECU-level diagnostics and ASAM-compliant error reporting |
| Thermal shutdown with hysteresis | Prevents latch-up during sustained overload; automatic recovery after cooling below 140 °C threshold |

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, higher RDS(on) (12 mΩ vs. 9.5 mΩ), no analog current sense output | Lacks dual-channel integration and real-time current monitoring capability | Use when only one load requires switching and diagnostic depth is not required |
| TPS4H160-Q1 | Quad-channel, lower max current (8 A/channel), SPI interface only (no parallel IN pins) | Requires MCU firmware support for configuration; no direct CMOS enable pins | Preferred for scalable multi-load systems where SPI-based diagnostics and channel grouping are needed |
Compared with BTS724G and TPS4H160-Q1, PEB2046NVA3 uniquely balances dual-channel autonomy, analog current monitoring, and parallel logic interface-making it optimal for cost-sensitive, safety-aware dual-load applications without MCU resource overhead.

FAQ
What is the maximum allowable junction temperature for PEB2046NVA3?
The absolute maximum junction temperature is +175 °C. Thermal shutdown activates at +165 °C with 15 °C hysteresis, allowing safe recovery before reaching destructive limits. PCB copper area and thermal vias under the exposed pad must meet Infineon's recommended layout guidelines to sustain 12 A continuous per channel.
Does PEB2046NVA3 support PWM dimming of LED loads?
Yes-it supports PWM frequencies up to 2 kHz with controlled slew rate to limit EMI, and maintains accurate current sensing during modulation. However, it is not optimized for high-frequency LED drivers (>10 kHz); use dedicated LED drivers for flicker-free illumination applications.
Can the IS1 and IS2 outputs be connected to a single ADC input multiplexed in time?
No-IS1 and IS2 are buffered analog outputs intended for simultaneous monitoring. Multiplexing introduces offset drift and sampling delay that compromises diagnostic accuracy. Each output must connect to a dedicated ADC channel or use an external analog multiplexer with matched gain/offset calibration.
Is there a recommended external capacitor for VBB decoupling?
Infineon specifies a minimum 10 µF ceramic capacitor (X7R, 25 V rating) placed within 5 mm of the VBB pin, plus a 100 nF ceramic capacitor in parallel. This combination suppresses high-frequency noise from inductive load switching and ensures stable gate drive during transient events.
