Infineon Technologies TLE5206-2GP

Overview

TLE5206-2GP from Infineon is a monolithic 5 A continuous, 6 A peak H-bridge power IC built on SPT® technology, integrating bipolar/CMOS control logic and DMOS output stages for bidirectional DC motor control. It supports forward, reverse, and two brake modes via two TTL/CMOS-compatible inputs, features integrated freewheeling diodes, 200 mΩ typical R_DS(on) per switch at 25 °C, and operates up to 40 V supply with −40 °C to 150 °C junction temperature range. Used in automotive seat/mirror actuators and industrial valve drivers.

For engineers reviewing the TLE5206-2GP datasheet, TLE5206-2GP pinout, TLE5206-2GP application, or TLE5206-2GP equivalent, key selection criteria include its dual-channel short-circuit protected outputs, open-drain error flag (EF), undervoltage lockout, thermal shutdown with hysteresis, and PG-DSO-20-37 package thermal resistance of 5 K/W (junction-to-case).

Technical Context

The device implements a fully integrated DMOS H-bridge with independent high-side and low-side switches per channel, controlled by Schmitt-trigger inputs with hysteresis to reject noise. Each output includes current limiting and real-time fault detection for short-circuit-to-ground, short-circuit-to-VS, and overload conditions.

Protection logic enforces strict shoot-through prevention via cross-conduction blocking: when one transistor is active, the complementary transistor in the same half-bridge is disabled. Faults trigger a 50 µs delay before global output disable and EF assertion (open-drain low), resettable only by toggling IN1/IN2 to a non-fault state-except for OUT1–OUT2 short circuits, which remain undetectable.

FAQ

What is the maximum allowable supply voltage for continuous operation?

The TLE5206-2GP supports continuous operation up to 40 V on the VS pin, with absolute maximum rating confirmed at 40 V (DC). Transient spikes up to 41 V are permitted for ≤500 ms per datasheet Section 3.1. Exceeding 40 V risks permanent damage to internal DMOS structures and protection circuitry.

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

During overtemperature shutdown (>150 °C junction), the EF pin is actively pulled low (open-drain sink) after thermal hysteresis delay, while all four output transistors are simultaneously disabled. The flag remains low until both IN1 and IN2 are toggled to a valid non-fault state - unlike short-circuit faults, no automatic recovery occurs upon cooling alone.

Can the TLE5206-2GP drive inductive loads without external freewheeling diodes?

Yes - the device integrates bidirectional freewheeling diodes across each DMOS switch, enabling safe commutation of inductive DC motors without external diodes. This is validated for standard brushed motor loads; however, highly reactive or resonant loads may still require additional snubbing depending on layout parasitics and switching frequency.

Is the PG-DSO-20-37 package lead-free and RoHS compliant?

Yes - the TLE5206-2GP is marked as a Green Product and fully RoHS compliant per EU Directive 2011/65/EU, with lead-free terminations and halogen-free molding compound. The PG-DSO-20-37 package meets JEDEC J-STD-020 moisture sensitivity level MSL-3 and supports standard reflow profiles up to 260 °C peak.
