Infineon Technologies IFX007TAUMA1

Overview

IFX007TAUMA1 from Infineon is a monolithic high-current PN half-bridge IC integrating a p-channel high-side MOSFET (R_DS(on) typ. 5.3 mΩ), an n-channel low-side MOSFET (R_DS(on) typ. 4.7 mΩ), and a logic-level driver with diagnostics, all in a single PG-TO263-7-1 package. It delivers 55 A min. current limitation, operates up to 40 V, and enables compact, EMI-optimized PWM motor drives in industrial automation.

For engineers reviewing the IFX007TAUMA1 datasheet, IFX007TAUMA1 pinout, IFX007TAUMA1 application, or IFX007TAUMA1 equivalent, this device is selected for protected high-current half-bridge switching where charge-pump elimination, integrated slew-rate control, status-flag diagnosis, and latch-type overtemperature shutdown are required.

Technical Context

The IFX007TAUMA1 implements a three-die NovalithIC™ architecture: separate p-channel HS and n-channel LS vertical power MOSFETs mounted on a common lead frame, plus a dedicated driver IC - eliminating external charge pumps and enabling precise dead-time generation and logic-level interfacing. Its dual-MOSFET topology supports active freewheeling and high-frequency PWM operation.

Protection is hardware-based and autonomous: undervoltage shutdown triggers below 8 V, overtemperature shutdown latches at 150 °C, and switched-mode current limitation activates at ≥55 A with fast response. The IS pin provides analog current-sense output and digital fault flag signaling simultaneously.

FAQ

What is the function of the SR pin on IFX007TAUMA1?

The SR (Slew Rate) pin allows external resistor programming of the dV/dt for both high-side and low-side MOSFETs. Connecting a resistor between SR and GND sets the switching edge rate, directly controlling electromagnetic interference during turn-on/turn-off. This hardware-based adjustment avoids firmware overhead and ensures consistent EMI performance across temperature and voltage variations.

Does IFX007TAUMA1 support 100% duty cycle operation?

Yes - the p-channel high-side MOSFET enables true 100% duty cycle operation without charge-pump dependency. Unlike n-channel HS solutions, it maintains gate drive integrity even during extended ON periods, making it suitable for applications like holding brakes or continuous DC motor excitation where uninterrupted conduction is required.

How does the IS pin provide both current sense and fault indication?

The IS pin outputs an analog voltage proportional to load current (typically 0.5 V/A) under normal operation, while simultaneously functioning as an open-drain fault flag. During overcurrent, overtemperature, or undervoltage events, the pin pulls low - allowing a single microcontroller ADC input and GPIO interrupt to monitor both analog current and digital fault status without additional components.

What thermal considerations apply to the PG-TO263-7-1 package?

The PG-TO263-7-1 exposes the drain pad (pins 4/8) for direct thermal attachment to a heatsink or copper pour. With R_thJC(HS) = 0.55 K/W and R_thJC(LS) = 1.1 K/W, effective thermal design requires ≥200 mm² of 2-oz copper connected via ≥6 thermal vias to inner layers. Junction-to-ambient resistance is 19 K/W on a standard 2s2p FR4 board - derating is required above 85°C ambient unless forced-air cooling is applied.
