Product details

Overview

TLE52052AKSA1 from Infineon is a monolithic power H-bridge IC for bidirectional DC motor control, featuring DMOS output stages, integrated freewheeling diodes, TTL/CMOS-compatible dual inputs (IN1/IN2), open-drain error flag (EF), and operation up to 40 V supply with 5 A continuous current capability. It supports forward, reverse, brake, and high-impedance modes in automotive-grade packaging.

For engineers reviewing the TLE52052AKSA1 datasheet, TLE52052AKSA1 pinout, TLE52052AKSA1 application, or TLE52052AKSA1 equivalent, key selection criteria include R_DS(on) (200 mΩ @ 25 °C), short-circuit and open-load diagnosis, overtemperature protection with hysteresis, undervoltage lockout, and AEC-Q100 qualification for motor drive reliability.

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 diodes. Its dual-input Schmitt-trigger interface provides noise immunity, while internal current limiting and thermal shutdown ensure robust fault handling.

Each output channel features independent short-circuit detection to VS or GND, plus open-load sensing via 10 kΩ pull-up/pull-down resistors on OUT1/OUT2. Faults trigger a 50 µs delay before disabling all outputs and asserting EF low - resettable only by toggling IN1/IN2.

Key Specifications

Parameter	Value and Actual Design Meaning
Continuous Output Current	5 A per channel - enables direct driving of medium-power DC motors without external heatsinking in TO220-7 package.
R_DS(on) (per switch)	200 mΩ @ 25 °C - minimizes conduction loss and thermal stress during sustained PWM operation.
Supply Voltage Range	Up to 40 V - supports 12 V and 24 V automotive battery systems with transient tolerance.
Operating Junction Temp	−40 °C to +150 °C - qualified for under-hood automotive environments with thermal hysteresis shutdown.
Error Flag Output	Open-drain EF pin - sinks current on fault (short, overload, overtemp, open load) for direct MCU interrupt signaling.
Input Compatibility	TTL/CMOS with hysteresis - ensures reliable logic-level interfacing across voltage domains without external level shifters.
Protection Functions	Short-circuit (VS/GND), overload, open-load, UVLO, overtemperature - eliminates need for discrete protection circuitry.

Pinout & Package

Package: PG-TO220-7-11 (thermally enhanced, tab-connected to GND). Pin 4 is internally connected to metal tab and serves as primary thermal path and ground reference.

Pin/Terminal	Circuit Role	Design Meaning
OUT1 (Pin 1)	H-bridge high-side output 1	Drives motor terminal A; short-circuit protected with integrated freewheeling diode to GND/VS.
EF (Pin 2)	Open-drain error flag	Sinks current when fault occurs (short, overload, open load, overtemp); requires external pull-up.
IN1 (Pin 3)	Logic input 1	TTL/CMOS-compatible Schmitt-trigger input controlling OUT1/OUT2 state per truth table.
GND (Pin 4)	Power and signal ground	Internally tied to metal tab; primary return path for load current and thermal dissipation.
IN2 (Pin 5)	Logic input 2	Second TTL/CMOS input; combined with IN1 defines motor direction, brake, or Hi-Z mode.
S (Pin 6)	Current sense enable	Not used in standard operation; connects to internal current-sense amplifier (not accessible in this variant).
V (Pin 7)	Supply voltage input	Connects to 12–40 V battery rail; requires local ceramic blocking capacitor to GND.

Key Features

Feature	Design Value
No crossover current	Internal timing prevents simultaneous high-side/low-side conduction - eliminates shoot-through risk without external dead-time control.
Integrated freewheeling diodes	Eliminates need for four external diodes - reduces PCB area, BOM count, and layout complexity in motor drive circuits.
Open-load diagnosis	Detects disconnected motor windings via internal 10 kΩ pull-up (OUT1) and pull-down (OUT2) - prevents false activation and enables system-level diagnostics.
AEC-Q100 qualified	Qualified to Grade 1 (−40 °C to +125 °C ambient) - meets automotive reliability requirements for body electronics and chassis applications.
Green product (RoHS)	Lead-free and halogen-free construction - compliant with EU RoHS Directive 2011/65/EU and automotive ELV requirements.

Equivalent & Alternatives

The following parts are listed as comparable options for similar H-bridge motor driver applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
BTS7960B	Higher current (43 A peak), no integrated open-load detection, larger TO263-7 package	Targeted at high-power industrial actuators, not optimized for compact automotive modules	Select when >10 A peak current required and board space allows larger footprint
VNH7040AS	Lower R_DS(on) (120 mΩ), SPI diagnostic interface instead of open-drain EF, same TO220-7 package	Requires MCU with SPI support; better suited for systems needing detailed fault registers	Select when advanced diagnostics (e.g., current measurement, temperature code) are prioritized over simplicity

Compared with BTS7960B and VNH7040AS, TLE52052AKSA1 offers optimal balance of compact TO220-7 form factor, integrated open-load sensing, and automotive-grade protection - ideal for cost-sensitive, space-constrained DC motor modules where discrete diagnostics are unnecessary.

FAQ

What is the maximum allowable supply voltage for continuous operation?

The TLE52052AKSA1 supports continuous operation up to 40 V supply voltage. Transient spikes beyond 40 V are tolerated per AEC-Q100 stress testing, but sustained operation above this limit risks permanent damage to the DMOS output stages and internal protection circuitry.

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

Open-load detection uses internal 10 kΩ pull-up on OUT1 and 10 kΩ pull-down on OUT2. When no load connects them, OUT1 rises to VS and OUT2 falls to GND - detected by comparators that assert EF after 50 µs. No external resistors or sensors are needed.

Can the EF pin be directly connected to a 3.3 V microcontroller GPIO?

Yes - the EF pin is open-drain and rated for 5 V tolerant operation. A 4.7 kΩ pull-up resistor to 3.3 V is sufficient. The pin sinks ≤10 mA when active, compatible with standard MCU interrupt inputs without level-shifting.

Is thermal derating required when mounted on a 2-layer PCB without forced air?

Yes - at 25 °C ambient, full 5 A continuous current is supported only with proper copper pour (≥10 cm² on inner layer) and soldered tab connection. Without thermal enhancement, current must be reduced to ~3.2 A at 70 °C ambient per datasheet derating curves.
