Infineon Technologies TLE4208GXUMA1

Overview

TLE4208GXUMA1 from Infineon Technologies is a quad half-bridge driver IC designed for automotive DC motor control, featuring four independently controllable half-bridges (configured as two dual-half-bridge pairs), 0.8 A continuous output current per channel, 1.2 V typical total saturation voltage at 0.4 A and 25 °C, integrated short-circuit and overtemperature protection with diagnostic flag outputs, and AEC-Q100 qualification for under-hood applications.

For engineers reviewing the TLE4208GXUMA1 datasheet, TLE4208GXUMA1 pinout, TLE4208GXUMA1 application in motor control systems, or TLE4208GXUMA1 equivalent for automotive actuator drivers, this page delivers verified electrical specs, validated package mapping to PG-DSO-28, confirmed truth table behavior for CW/CCW/brake/standby modes, and real-world diagnosis logic for EF12/EF34 error flags.

Technical Context

The device implements two independent dual-half-bridge groups (HB1–HB2 and HB3–HB4), each with separate supply rails (VS12 and VS34) and inhibit inputs (INH12 and INH34), enabling flexible cascade configurations for up to three DC motors. Each half-bridge supports forward, reverse, brake (LL or HH), and high-impedance modes via CMOS/TTL-compatible inputs with hysteresis.

Fault detection is implemented via open-collector error flags EF12 and EF34, each reporting combined overtemperature or overvoltage conditions for its respective half-bridge pair. Diagnostics are latched until reset by toggling the corresponding INH input, and internal clamp diodes eliminate need for external flyback components.

FAQ

What is the maximum allowable supply voltage for VS12 and VS34?

The absolute maximum rating for VS12 and VS34 is 45 V, with transient tolerance up to that level for durations under 0.5 seconds. Continuous operation must remain within the functional range of 5.5 V to 28 V, as specified in Section 4.2 of the datasheet. Exceeding 45 V risks permanent damage, even with short duration.

How does the EF12 error flag behave during an overtemperature event?

EF12 goes low when either overtemperature or overvoltage is detected on half-bridges 1 and 2. The flag remains latched low until INH12 is toggled (high→low→high), regardless of whether the fault condition persists. This behavior enables reliable fault capture in microcontroller-based systems without continuous polling.

Can TLE4208GXUMA1 drive a single full-bridge motor using only two half-bridges?

Yes - half-bridges 1 and 2 (or 3 and 4) can be configured as a full-bridge by connecting OUT1 and OUT2 to opposite motor terminals, with VS12 supplying the bridge. The truth table in Section 3.2 defines CW, CCW, and brake (LL/HH) modes explicitly for this configuration, and no external components are needed beyond decoupling capacitors.

Is the PG-DSO-28 package thermally enhanced compared to standard SOIC-28?

Yes - the PG-DSO-28 package features an exposed thermal pad on the underside, directly soldered to the PCB ground plane, achieving a junction-to-ambient thermal resistance (R_thjA) of 65 K/W. This is significantly lower than standard SOIC-28 packages (~100+ K/W), enabling sustained 0.8 A operation without additional heatsinking in automotive ambient conditions.
