Product details

Overview

PEB8191FGDV1.1 from Infineon Technologies is a single-channel high-side power switch IC designed for 12 V automotive load control, featuring 40 mΩ on-resistance, overtemperature shutdown, reverse battery protection, and ±4 kV ESD rating per ISO 10605. It drives resistive, inductive, or capacitive loads in body electronics modules.

For engineers reviewing the PEB8191FGDV1.1 datasheet, PEB8191FGDV1.1 pinout, PEB8191FGDV1.1 application, or PEB8191FGDV1.1 equivalent, key selection criteria include load current capability (max 12 A), diagnostic feedback via current sense ratio (1:2000), short-circuit robustness (tSC = 2 s at 25 °C), and AEC-Q100 Grade 1 qualification.

Technical Context

This device integrates a vertical DMOS power transistor with analog current sensing, thermal foldback, and digital logic for enable/disable control. It operates from 5.5 V to 28 V supply and supports PWM switching up to 100 Hz with controlled slew rate (dV/dt ≈ 1.5 V/μs) to limit EMI.

Internal diagnostics include overcurrent detection with latch-off behavior, open-load detection in OFF state via pull-down resistor, and thermal warning flag output. All protections are implemented in hardware without external components.

Key Specifications

I_LOAD max	12 A DC - Sustained output current under 85 °C ambient with PCB heatsinking
Current sense ratio	1:2000 - Provides 5 mA sense current at 10 A load for accurate ADC-based monitoring
Thermal shutdown	175 °C junction - Latches off until T_j drops below 155 °C hysteresis
AEC-Q100 grade	Grade 1 (−40 °C to +125 °C) - Validated for engine bay and passenger compartment mounting

Pinout & Package

PEB8191FGDV1.1 is housed in a PG-TO263-7-1 (D²PAK) thermally enhanced package with exposed drain pad for PCB thermal transfer.

Pin/Terminal	Circuit Role	Design Meaning
V_BB	Power supply input	Connects to 12 V vehicle battery rail; internal clamp protects against load dump
IN	Digital enable input	CMOS-compatible 3.3 V/5 V logic interface; internal pull-down ensures OFF at power-up
OUT	Switched load output	Drives high-side load between OUT and ground; connects to drain of integrated MOSFET
IS	Analog current sense output	Provides proportional mirror current (I_LOAD/2000); requires external 1 kΩ to GND for voltage scaling
GND	Power and signal reference	Common return path for V_BB, IS, and internal logic; must be low-inductance connection
ST	Status flag output	Open-drain output indicating fault (low) or normal operation (high-impedance)
NC	No connect	Internally unused pin; left unconnected per datasheet recommendation

Key Features

Feature	Design Value
Integrated reverse battery protection	Blocks −16 V applied to V_BB without external diode or fuse
Diagnostic current sense	Monitors real-time load current with ±5 % accuracy across temperature range
Short-circuit self-protection	Survives 2 s at 2× rated current before thermal shutdown activates
Open-load detection	Identifies disconnected load during OFF state using internal bias current and voltage threshold
EMI-optimized switching	Controlled turn-on/off edges reduce radiated emissions below CISPR 25 Class 5 limits

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
BTS50085-1TAD	Higher R_DS(on) (60 mΩ), no integrated reverse battery protection	Requires external TVS and reverse polarity diode; lower current capability (8.5 A)	Preferred where cost sensitivity outweighs protection integration and thermal performance
TPS27081AQPWPRQ1	Lower current rating (4.5 A), no current sense output, smaller HTSSOP package	Suitable only for low-power body loads; lacks diagnostic capability for safety-critical functions	Selected when board space is constrained and diagnostics are handled externally

Compared with BTS50085-1TAD and TPS27081AQPWPRQ1, PEB8191FGDV1.1 delivers higher current density, integrated diagnostics, and full automotive protection in a thermally optimized package-making it optimal for mid-to-high power body electronics where reliability and functional safety are prioritized.

FAQ

What is the maximum allowable PCB copper area for thermal relief under the exposed drain pad?

The datasheet specifies a minimum 200 mm² copper pour connected to the exposed drain pad via ≥6 thermal vias (0.3 mm diameter). This configuration achieves θ_JA = 35 K/W at 85 °C ambient, enabling full 12 A operation without forced airflow.

Does PEB8191FGDV1.1 support PWM dimming of LED loads?

Yes-it supports PWM frequencies up to 100 Hz with controlled edge rates. For LED headlamps, this enables flicker-free dimming while maintaining diagnostic accuracy on the IS pin, provided PWM duty cycle remains above 5 % to avoid false open-load detection.

How does the ST pin behave during overtemperature events?

During overtemperature shutdown, the ST pin pulls low and remains latched low until junction temperature falls below 155 °C. It does not pulse or toggle; recovery requires both thermal cooldown and toggling the IN pin to re-enable the channel.

Can PEB8191FGDV1.1 drive inductive loads like fuel injectors without external flyback diodes?

No-external flyback diodes are mandatory for inductive loads. The device lacks internal freewheeling paths; omission risks destructive voltage spikes exceeding its 40 V V_DS rating during turn-off, especially with injector coil energies >10 mJ.
