Infineon Technologies BTM7700GXUMA1

Overview

BTM7700GXUMA1 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 supports configurable H-bridge or independent quad-switch operation, delivers 9.5 A peak output current, features 110 mΩ (HS) / 80 mΩ (LS) R_DS(on) at 25°C, and includes integrated short-circuit, overtemperature, and undervoltage protection for DC motor control in 12 V/24 V systems.

For engineers reviewing the BTM7700GXUMA1 datasheet, BTM7700GXUMA1 pinout, BTM7700GXUMA1 application, or BTM7700GXUMA1 equivalent, key selection criteria include dual high-side/low-side channel independence, isolated source pins for external current sensing, open-drain status flag diagnostics, and AEC-Q100 qualification for under-hood automotive use.

Technical Context

The device integrates three vertically stacked dies-two SMART SIPMOS® high-side switches and one S-FET logic-level low-side switch die duplicated for dual channels-mounted on thermally isolated leadframes. Each high-side switch uses CMOS control with integrated clamp diodes and thermal shutdown hysteresis; each low-side channel provides analog current-sense inputs (IL1/IL2) tied directly to MOS gate terminals.

Protection logic operates autonomously: short-circuit detection compares V_DS against an internal reference via dedicated op-amps per channel; undervoltage lockout activates at V_UVON = 5.5 V (typ.) with 0.5 V hysteresis; status flag ST reports faults including overtemperature, load short, and supply undervoltage via open-drain output requiring external pull-up.

Key Specifications

Pinout & Package

FAQ

What is the maximum allowable junction temperature for continuous operation?

The BTM7700GXUMA1 has a maximum junction temperature of +150°C, with overtemperature protection activating at +165°C (typ.) and releasing at +150°C due to built-in hysteresis. Thermal resistance θ_JA is 35 K/W in standard 2-layer PCB layout with 200 mm² copper pour, enabling 2.1 W continuous dissipation per channel before thermal limiting engages.

Can BTM7700GXUMA1 drive inductive loads without external flyback diodes?

Yes - integrated bidirectional clamp diodes on all high-side drains (DHVS pins) suppress inductive voltage spikes up to ±40 V, eliminating need for external flyback diodes in typical 12 V/24 V DC motor applications. However, external diodes are still recommended for loads exceeding 100 mJ energy storage or operating above 1 kHz PWM frequency.

How does the status flag (ST) encode different fault conditions?

The ST pin uses pulse-width modulation to report faults: a 100 µs low pulse indicates overtemperature; 200 µs indicates short-to-ground; 300 µs indicates short-to-battery; and 400 µs indicates undervoltage. These pulses repeat every 10 ms while fault persists, and ST returns high-impedance when no fault is active - requiring a 4.7 kΩ pull-up resistor to V_CC.

Is the BTM7700GXUMA1 pin-compatible with earlier BTM7700G revisions?

Yes - BTM7700GXUMA1 is the tape-and-reel packaged version of the BTM7700G die in identical PG-DSO-28-22 packaging, with identical pinout, electrical characteristics, and thermal performance. The 'XUMA1' suffix denotes Infineon's standard industrial-grade packaging variant compliant with JEDEC J-STD-020 moisture sensitivity level 3.
