Infineon Technologies BTM7752GXUMA1

Overview

BTM7752GXUMA1 from Infineon Technologies is a fully integrated automotive-grade high-current H-bridge IC for bidirectional DC motor control, featuring dual p-channel high-side and dual n-channel low-side MOSFETs in one package, 150 mΩ typical R_DS(on) @ 25 °C, 12 A typical current limit, and logic-level inputs with integrated dead time generation. It enables compact, EMI-optimized PWM motor drives up to 25 kHz in power seats and HVAC actuators.

For engineers reviewing the BTM7752GXUMA1 datasheet, BTM7752GXUMA1 pinout, BTM7752GXUMA1 application, or BTM7752GXUMA1 equivalent, key selection criteria include its AEC-Q100 qualification, integrated current sense and status flag, overtemperature latch behavior, and elimination of external charge pump via p-channel high-side switches.

Technical Context

The BTM7752GXUMA1 implements a four-switch H-bridge topology with independent gate drivers for each half-bridge, using p-channel high-side switches to avoid charge-pump circuitry and reduce EMI. Its digital logic interface accepts 3.3 V/5 V-compatible IN1/IN2/INH signals and delivers real-time fault diagnosis via IS pin.

Protection architecture includes latch-type overtemperature shutdown (T_j > 150 °C), overvoltage lockout (>45 V), undervoltage shutdown (<5.5 V), switch-mode current limitation (12 A typ.), and short-circuit detection with automatic recovery delay. All protections operate within 8–28 V supply range and -40 °C to +150 °C junction temperature.

Key Specifications

Pinout & Package

BTM7752GXUMA1 uses PG-DSO-36-29 package: 36-pin exposed-pad SOIC with VS and GND pins distributed across multiple locations for low-inductance power routing and thermal dissipation. The exposed thermal pad must be soldered to PCB ground plane.

FAQ

What is the maximum continuous output current supported by BTM7752GXUMA1?

The BTM7752GXUMA1 supports 4 A continuous output current per channel at T_c = 85 °C with adequate PCB copper area, based on its 29 K/W junction-to-soldering-point thermal resistance and 150 mΩ R_DS(on). At higher ambient temperatures or reduced copper, derating applies per Figure 4 and thermal simulation data in section 5.3.

Does BTM7752GXUMA1 require an external charge pump circuit?

No. BTM7752GXUMA1 uses p-channel MOSFETs for high-side switching, eliminating the need for an external charge pump. This reduces component count, board area, and EMI generation - a key differentiator versus n-channel high-side H-bridges like the BTN7960B.

How does the IS pin function during normal operation and fault conditions?

During normal operation, the IS pin outputs an analog voltage proportional to load current (100 mV/A). During overcurrent, overtemperature, or short-circuit events, it asserts an open-drain error flag while maintaining current-sense functionality - enabling simultaneous fault detection and closed-loop current control without additional sensing hardware.

Is BTM7752GXUMA1 pin-compatible with earlier BTM7752 variants?

Yes. BTM7752GXUMA1 is the tape-and-reel packaged version of the BTM7752G, sharing identical pinout, electrical characteristics, and thermal profile with the original PG-DSO-36-29 footprint. No PCB redesign is needed when migrating from BTM7752G to BTM7752GXUMA1.
