Infineon Technologies TLE52062SAKSA1

Overview

TLE52062SAKSA1 from Infineon is a monolithic H-bridge power IC for DC motor control, integrating dual DMOS output stages with TTL/CMOS-compatible inputs, 5 A continuous current capability, 40 V max supply voltage, and integrated freewheeling diodes. It supports forward, reverse, and two brake modes in automotive body electronics and industrial actuators.

For engineers reviewing the TLE52062SAKSA1 datasheet, TLE52062SAKSA1 pinout, TLE52062SAKSA1 application, or TLE52062SAKSA1 equivalent, key selection criteria include R_DS(on) (200 mΩ), short-circuit protection response time (50 µs), thermal shutdown threshold (150 °C), and open-drain error flag behavior under fault conditions.

Technical Context

The device implements a fully integrated DMOS H-bridge with independent high-side and low-side drivers per channel, using SPT® multi-technology process to co-integrate bipolar/CMOS logic and power DMOS on one die. Input Schmitt triggers with hysteresis ensure noise-immune logic-level control.

Protection architecture includes dual independent diagnosis circuits monitoring each output for short-to-ground, short-to-VS, overload (I_SDL trip), and overtemperature (T_j > 150 °C), all triggering simultaneous output disable and EF pin pull-down within 50 µs.

FAQ

What is the maximum allowable supply voltage for continuous operation?

The TLE52062SAKSA1 supports continuous operation up to 40 V DC on the VS pin. Absolute maximum rating allows brief (≤500 ms) exposure to 40 V, but sustained operation should remain within 36 V to maintain margin against load dump transients common in 24 V automotive systems. Exceeding 40 V risks irreversible damage to the DMOS output stages.

How does the error flag (EF) behave during overtemperature shutdown?

When junction temperature exceeds 150 °C, the thermal protection circuit asserts EF low within 50 µs while simultaneously disabling all four DMOS transistors. EF remains low until both IN1 and IN2 inputs change state (e.g., toggle from HH to LL), which resets the latch. No external pull-up is required as internal weak pull-up ensures EF returns high after reset.

Can TLE52062SAKSA1 drive inductive loads without external freewheeling diodes?

Yes. The device integrates bidirectional freewheeling diodes for both OUT1 and OUT2, enabling safe commutation of brushed DC motors and solenoids without external diodes. These diodes handle energy recirculation during PWM switching and inductive kickback, provided layout minimizes trace inductance and local decoupling capacitance (≥100 nF ceramic + ≥10 µF electrolytic) is placed near the V pin.

Is there a difference between TLE52062SAKSA1 and TLE52062G?

Yes. TLE52062SAKSA1 uses the PG-TO220-7-11 package with isolated tab and lead-free finish, while TLE52062G uses PG-TO263-7-1. Both share identical electrical specifications and pinout mapping, but differ in thermal performance (R_th,j-c = 3 K/W vs. 5 K/W) and mounting method (through-hole vs. surface-mount). The "SAKSA1" suffix denotes Infineon's standard automotive packaging variant with extended temperature screening.
