Infineon Technologies PEF2015TV1.2

Overview

PEF2015TV1.2 from Infineon Technologies is a single-channel 1.2 A high-side power switch in PG-TO252-3 package, featuring overtemperature shutdown, current limiting, and reverse battery protection. It operates from 5.5 V to 28 V supply, supports 1.2 A continuous load current, and delivers typical on-resistance of 140 mΩ at 25 °C. Used in automotive body control modules for interior lighting and window lift actuation.

For engineers reviewing the PEF2015TV1.2 datasheet, PEF2015TV1.2 pinout, PEF2015TV1.2 application, or PEF2015TV1.2 equivalent, key selection criteria include thermal shutdown threshold (165 °C), diagnostic enable/disable capability via IN pin logic, short-circuit robustness under 12 V battery conditions, and AEC-Q100 Grade 1 qualification status.

Technical Context

This device integrates a vertical DMOS transistor with embedded protection circuitry including thermal foldback, overcurrent detection with current-sense output, and open-load detection. The IN pin accepts TTL/CMOS-compatible logic levels, while the IS pin provides proportional analog current sense output (1:2000 ratio) for real-time load monitoring.

It implements adaptive current limiting that reduces output current during sustained overload to maintain safe junction temperature, and features fast turn-off time (typ. 2.5 µs) to support PWM-controlled loads without shoot-through risk in multi-switch configurations.

FAQ

What is the maximum allowable junction temperature for continuous operation?

The PEF2015TV1.2 has a maximum junction temperature of 150 °C for continuous operation. Thermal shutdown activates at 165 °C to prevent permanent damage. Derating curves in the datasheet specify 1.2 A maximum current at 70 °C ambient with standard 2-layer PCB heatsinking and 10 thermal vias under the exposed drain pad.

Does the IS pin require an external pull-down resistor?

Yes, the IS pin requires an external pull-down resistor (typically 10 kΩ to GND) to establish a defined low state when no load current flows. Without it, leakage current causes floating voltage that interferes with open-load detection and current measurement accuracy. The resistor also sets the gain for analog current sensing when used with an op-amp.

Can PEF2015TV1.2 be used in parallel for higher current capacity?

No, PEF2015TV1.2 is not designed for paralleling. Mismatches in R_DS(on) and thermal coupling cause current imbalance, leading to premature thermal shutdown in one device. For higher current, select a single-channel part with appropriate rating (e.g., BTS50085-1TAD) or use independent channels with separate control logic.

Is reverse battery protection active during sleep mode?

Yes, reverse battery protection remains fully functional even when the IN pin is low (device disabled), because it relies on internal MOSFET body diode orientation and charge pump circuitry independent of control logic. This ensures protection during vehicle battery replacement or jump-start scenarios regardless of ECU power state.
