Infineon Technologies TLE52062AKSA1

Overview

TLE52062AKSA1 from Infineon is a monolithic 5 A continuous, 40 V-rated H-bridge power IC for DC motor control, featuring integrated DMOS output stages, internal freewheeling diodes, and dual TTL/CMOS-compatible control inputs (IN1/IN2) enabling forward, reverse, and two brake modes. It delivers typ. 200 mΩ R_DS(on) per switch at 25 °C and operates across −40 °C to 150 °C junction temperature in automotive motor actuation systems.

For engineers reviewing the TLE52062AKSA1 datasheet, TLE52062AKSA1 pinout, TLE52062AKSA1 application, or TLE52062AKSA1 equivalent, key selection criteria include its 5 A continuous current capability, open-drain error flag (EF) for fault reporting, short-circuit and overtemperature protection with 50 µs response, and compatibility with 40 V supply rails in brushed DC motor drive circuits.

Technical Context

The device implements a fully integrated DMOS H-bridge with independent high-side and low-side drivers per channel, controlled via Schmitt-trigger inputs with hysteresis. Its diagnosis circuitry monitors each output for short-to-ground, short-to-VS, overload (I_SD trippoint), and thermal shutdown (>150 °C).

Operation modes-forward (IN1=H, IN2=L), reverse (IN1=L, IN2=H), brake-low (IN1=L, IN2=L), and brake-high (IN1=H, IN2=H)-are selected without external logic. Crossover current is eliminated by interlocked gate control, and all faults trigger simultaneous output disable plus EF assertion within 50 µs.

FAQ

What is the maximum allowable supply voltage for TLE52062AKSA1?

The absolute maximum supply voltage (V_S) is 40 V for continuous operation. Short-duration transients up to 40 V are permitted for ≤500 ms, but operation beyond this limit risks irreversible damage. The UVLO circuit activates at V_S,ON ≈ 5.5 V and disables outputs below V_S,OFF ≈ 4.5 V to prevent undefined behavior during brownout conditions.

How does the error flag (EF) behave during a short-circuit event?

During any detectable fault-including short-to-GND, short-to-V_S, overload, or overtemperature-the EF pin pulls low (open-drain sink) within 50 µs. The flag remains asserted until both IN1 and IN2 inputs change state (e.g., toggle from L/L to H/L), which resets the internal latch and releases EF to high-impedance. Short-circuit between OUT1 and OUT2 is not detectable.

Can TLE52062AKSA1 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 clamp inductive kickback to GND and V_S, eliminating voltage spikes that could damage the IC or adjacent circuitry.

Is thermal derating required when operating at elevated ambient temperatures?

Yes. With R_th,jC = 3 K/W and R_th,jA = 65 K/W (TO220-7-11), continuous 5 A operation requires heatsinking to maintain T_j ≤ 150 °C. At 85 °C ambient, maximum sustainable current drops to ~3.8 A without forced airflow; full 5 A rating assumes case temperature ≤ 75 °C via appropriate heatsink design.
