Infineon Technologies TLE72093RAUMA1

Overview

TLE72093RAUMA1 from Infineon Technologies is an intelligent full H-bridge IC for bidirectional DC motor control in safety-critical automotive applications, featuring 5–28 V operating supply, 150 mΩ typical R_DS(on) per channel at 25 °C, 5 A continuous DC load current (T_C < 100 °C), integrated chopper current limitation at 6.6 A ± 1.1 A, and short-circuit shutdown above 8 A.

For engineers reviewing the TLE72093RAUMA1 datasheet, TLE72093RAUMA1 pinout, TLE72093RAUMA1 application, or TLE72093RAUMA1 equivalent, key selection considerations include diagnostic mode configuration (SPI vs. status flag), thermal derating behavior (2.5 A min at T_j > T_ILR), tristate output behavior during fault conditions, and PG-DSO-20-65 package thermal performance under pulsed load conditions.

Technical Context

The TLE72093RAUMA1 integrates four n-channel DMOS power transistors with internal charge pump for high-side gate drive, enabling full H-bridge operation without external bootstrap components. It implements dual protection logic: fast 2 μs short-circuit detection to ground (SCG1/SCG2) and blanking-time-based short-to-VS detection (SCB1/SCB2) using integrated sense cells on low-side switches.

Diagnostic mode is selected via DMS pin voltage: GND enables TTL-compatible status-flag output on SCK/SF pin; 5 V enables SPI interface (SDI/SDO/SCK/SF/CSN) for 8-bit register access to fault flags including SCOL (short across load), OT (over-temperature), and UV (under-voltage). All faults force outputs into tristate.

FAQ

What diagnostic modes does the TLE72093RAUMA1 support, and how are they configured?

The device supports two diagnostic modes: status-flag output and SPI interface. Configuration is controlled solely by the voltage on pin 12 (DMS): grounding DMS selects status-flag mode (SCK/SF pin outputs fault indicator), while applying 5 V to DMS enables SPI mode (SDI/SDO/SCK/SF/CSN active). No external resistors or firmware configuration is required-mode selection is hardware-determined at power-up.

How does the chopper current limitation behave under elevated junction temperature?

The chopper current limit decreases linearly from 6.6 A ± 1.1 A at T_j = T_ILR to 2.5 A ± 1.1 A at T_j = T_SD, as defined in the datasheet's Figure 4. This thermal derating ensures safe operation without abrupt shutdown during sustained overload, allowing controlled torque reduction while maintaining motor controllability up to thermal shutdown threshold.

Can the TLE72093RAUMA1 drive inductive loads without external freewheeling diodes?

Yes-the device integrates bidirectional freewheeling diodes across each output transistor pair, enabling safe energy recirculation during PWM switching of inductive DC motors. These diodes clamp positive and negative voltage spikes caused by load inductance, eliminating the need for external flyback diodes in standard configurations.

What happens to the outputs during an over-temperature event?

When junction temperature exceeds T_SD, all four output transistors switch off and enter high-impedance (tristate) state immediately. The "Over-Temperature" (OT) bit is set in the internal status register (accessible via SPI) and held until cleared by host software or power cycle. Outputs remain disabled until temperature falls below hysteresis threshold and fault is reset.
