Infineon Technologies TLE52052GAUMA1

Overview

TLE52052GAUMA1 from Infineon is a monolithic 5-A H-bridge power IC with DMOS output stages for bidirectional DC motor control, featuring TTL/CMOS-compatible dual inputs (IN1/IN2), integrated freewheeling diodes, 200 mΩ typical R_DS(on) per switch at 25 °C, 40 V max supply voltage, and −40 °C to 150 °C junction temperature range. It supports forward, reverse, brake, and high-impedance modes in automotive body electronics.

For engineers reviewing the TLE52052GAUMA1 datasheet, TLE52052GAUMA1 pinout, TLE52052GAUMA1 application, or TLE52052GAUMA1 equivalent, key selection criteria include short-circuit protection timing (50 µs fault response), open-load diagnosis via internal 10 kΩ pull-up/pull-down resistors, error flag (EF) open-drain output behavior, and thermal shutdown hysteresis at 150 °C.

Technical Context

The device integrates bipolar/CMOS control logic and DMOS power transistors on a single SPT® die, enabling precise H-bridge switching without external flyback components. Its Schmitt-trigger inputs provide noise immunity, while independent diagnosis circuits monitor each output for short-to-ground, short-to-VS, overload (I_SDL trippoint), and open-load conditions.

Operation relies on complementary high-side/low-side transistor pairing with crossover-current prevention logic. The EF pin asserts low within 50 µs of fault detection and resets only upon input state change-except for OUT1–OUT2 short circuit, which requires external intervention.

FAQ

What is the function of the S pin on TLE52052GAUMA1?

The S pin is not functional in the TLE52052GAUMA1 variant and is designated as No Connect (N.C.) per the official datasheet pin mapping for PG-TO220-7-11. Unlike other variants in the TLE5205-2 family, this part does not implement current sensing; therefore, the S pin must remain unconnected and should not be tied to any voltage or ground node.

How does the open-load detection work without external components?

Open-load detection uses internal 10 kΩ pull-up on OUT1 and 10 kΩ pull-down on OUT2. When no motor is connected, OUT1 floats to VS and OUT2 to GND, creating distinct voltage states sensed by on-chip comparators. A 50 µs delay confirms the condition before asserting EF low-no external resistors or sensors are needed.

Can TLE52052GAUMA1 drive a 24 V DC motor with 3 A continuous current?

Yes. With a typical R_DS(on) of 200 mΩ per switch and 5 A continuous rating, the device delivers 3 A continuously at 24 V with ≤1.8 W total conduction loss (2 × I²R). Thermal performance remains within safe limits in PG-TO220-7-11 with minimal copper pour, per Infineon's thermal characterization data.

Is the EF pin compatible with 3.3 V microcontrollers?

Yes. The EF pin is an open-drain output that sinks current when active. A 3.3 V microcontroller GPIO can interface directly by connecting a 10 kΩ pull-up resistor to 3.3 V. The EF pin's VOL is ≤0.4 V at 3 mA sink current, ensuring reliable low-level detection by 3.3 V logic inputs.
