Infineon Technologies TLE52062GAUMA1

Overview

TLE52062GAUMA1 from Infineon is a monolithic 5 A continuous, 6 A peak H-bridge power IC for DC motor control, featuring dual DMOS output stages with integrated freewheeling diodes, 200 mΩ typical R_DS(on) per switch at 25 °C, 40 V max supply voltage, and AEC-Q100 qualification for automotive applications including power seat and window actuators.

For engineers reviewing the TLE52062GAUMA1 datasheet, TLE52062GAUMA1 pinout, TLE52062GAUMA1 application, or TLE52062GAUMA1 equivalent, this part supports TTL/CMOS-compatible dual-input logic, short-circuit and overtemperature protection with open-drain error flag (EF), brake-high/brake-low operation modes, and operates across −40 °C to 150 °C junction temperature range.

Technical Context

The TLE52062GAUMA1 integrates bipolar/CMOS control logic and DMOS power transistors on a single SPT® die, enabling precise H-bridge switching without external flyback diodes. Its Schmitt-trigger inputs with hysteresis ensure noise-immune logic-level interfacing, while independent diagnosis circuits monitor each output for short-to-ground, short-to-VS, overload, and thermal faults.

Operation follows a 2-bit truth table: IN1/IN2 = L/H drives counterclockwise rotation (OUT1=L, OUT2=H); H/L drives clockwise (OUT1=H, OUT2=L); L/L and H/H enable low-side and high-side braking respectively. Crossover current is eliminated via interlocked gate drive logic that prevents simultaneous conduction of source/sink transistors in the same half-bridge.

FAQ

What is the function of the EF (Error Flag) pin?

The EF pin is an open-drain output that pulls low during any detected fault condition - including output short-to-ground, short-to-VS, overload, undervoltage lockout, or junction temperature exceeding 150 °C. It remains low until the input logic state changes (e.g., toggling IN1 or IN2), which resets the flag. No external pull-down is needed; a pull-up resistor to MCU V_CC is required to generate a valid logic-high idle state.

Can TLE52062GAUMA1 drive inductive loads without external diodes?

Yes - the device integrates bidirectional freewheeling diodes across both OUT1 and OUT2 outputs, enabling safe commutation of brushed DC motors and solenoids without external flyback components. This integration eliminates four discrete diodes, reduces PCB footprint, and ensures matched diode characteristics across channels, critical for consistent brake behavior and EMI control.

What thermal derating applies above 85 °C ambient?

At ambient temperatures above 85 °C, continuous current must be reduced linearly based on R_thjA = 65 K/W and maximum T_j = 150 °C. For example, at 100 °C ambient, allowable power dissipation drops to ~1.5 W, limiting continuous current to approximately 3.9 A (using P = I² × 0.2 Ω). Derating curves are provided in Figure 12 of the official datasheet Rev. 1.1.

Is TLE52062GAUMA1 pin-compatible with other TLE5206 variants?

No - TLE52062GAUMA1 uses the PG-TO220-7-11 package with 7 leads in standard TO220 outline, whereas TLE5206-2GP (PG-DSO-20-37) and TLE5206-2G (PG-TO263-7-1) have different pin counts, layouts, and thermal pads. Pin mapping differs significantly: DSO-20 has 20 pins with multiple GND and NC terminals, and TO263-7 has reversed pin order and isolated tab. Direct replacement requires board redesign.
