Infineon Technologies BTM7710GXUMA1

Overview

BTM7710GXUMA1 from Infineon Technologies is a quad-channel automotive power switch IC integrating two high-side and two low-side D-MOS drivers in a single PG-DSO-28-22 package. It delivers 15 A peak current, features 70 mΩ typ. high-side R_DS(on) at 25°C and 40 mΩ typ. low-side R_DS(on), with integrated short-circuit, overtemperature, and undervoltage protection. It is designed for DC motor control in automotive body electronics such as seat adjusters and window lifters.

For engineers reviewing the BTM7710GXUMA1 datasheet, BTM7710GXUMA1 pinout, BTM7710GXUMA1 application, or BTM7710GXUMA1 equivalent, key selection criteria include configurable H-bridge/quad-switch topology, isolated source pins for external current sensing, open-drain status flag diagnostics, and AEC-Q100 qualification for under-hood use.

Technical Context

The device integrates three vertically stacked dies - one double high-side switch (SMART SIPMOS®) and two independent low-side switches (S-FET logic-level) - with physically separated drain leadframes to enable thermal and functional isolation. Each switch has dedicated analog current-sense inputs (IL1/IL2) and digital control inputs (IH1/IH2), supporting independent or coordinated switching.

Protection logic uses real-time V_DS monitoring via internal op-amps for short-circuit detection, junction-temperature-dependent current limiting, and hysteresis-based undervoltage lockout (V_UVON = 5.5 V, V_UVOFF = 4.8 V). The open-drain ST pin reports combined fault conditions including overtemperature, short-to-ground, and supply undervoltage.

Key Specifications

Pinout & Package

FAQ

What is the maximum junction temperature and thermal shutdown behavior?

BTM7710GXUMA1 shuts down high-side outputs at T_j = 175°C ±5°C and remains off until junction temperature drops to approximately 155°C due to built-in hysteresis. This prevents thermal oscillation during overload conditions and ensures safe recovery before reactivation. Thermal resistance R_thJA is 35 K/W in standard 2-layer PCB layout with 10 cm² copper pour.

Can BTM7710GXUMA1 drive inductive loads without external flyback diodes?

Yes - integrated clamp diodes protect high-side outputs against negative voltage spikes during inductive load turn-off. However, low-side switches require external freewheeling diodes when used in single-switch mode; in H-bridge configuration, the body diodes of complementary switches provide inherent freewheeling paths.

How does the status flag (ST) indicate specific fault conditions?

The ST pin is an open-drain output that pulls low for any active fault: overtemperature, short-to-ground, short-to-V_S, or undervoltage lockout. It does not encode fault type - discrete diagnosis requires monitoring IL1/IL2 analog signals or correlating timing of ST assertion with control inputs IH1/IH2 states.

Is BTM7710GXUMA1 pin-compatible with earlier BTM7710G versions?

Yes - BTM7710GXUMA1 is the tape-and-reel packaged version of the BTM7710G die, sharing identical pinout, electrical characteristics, thermal performance, and package outline (PG-DSO-28-22). The 'XUMA1' suffix denotes Infineon's standard commercial packaging variant for automated SMT assembly.
