Infineon Technologies TLE94110ELXUMA1

Overview

TLE94110ELXUMA1 from Infineon Technologies is a protected ten-channel half-bridge driver IC designed for automotive motion control, specifically HVAC flap DC motor actuation. It delivers 10 independently controllable half-bridge outputs, supports 3.3V/5V logic inputs with hysteresis, and integrates SPI-based diagnostics including overcurrent, open-load, and overtemperature detection. Its PG-SSOP-24 package enables compact placement in space-constrained body electronics modules.

For engineers reviewing the TLE94110ELXUMA1 datasheet, TLE94110ELXUMA1 pinout, TLE94110ELXUMA1 application, or TLE94110ELXUMA1 equivalent, key selection criteria include its 10-channel half-bridge architecture, 0.1 µA quiescent current in sleep mode, 5 MHz SPI interface with daisy-chain capability, and integrated cross-current and load-dump protection up to 40 V.

Technical Context

The TLE94110ELXUMA1 implements a distributed protection architecture across all ten half-bridge channels, with independent short-circuit, open-load (ON-state), and overtemperature monitoring per output. Each channel combines high-side and low-side MOSFET drivers with matched R_DS(on) of ≤1.8 Ω (HS) + ≤1.8 Ω (LS) at 150°C.

Its 16-bit SPI interface supports in-frame response and global error flag reporting, enabling fast system-level fault detection without polling. The device operates across 5.5–18 V supply range (VS), tolerates load dump up to 40 V, and features dual supply rails (VS1/VS2 and VDD) with separate undervoltage/overvoltage lockout thresholds.

FAQ

What is the maximum allowable supply voltage during load dump conditions?

The TLE94110ELXUMA1 supports a maximum supply voltage of 40 V under load dump conditions, as specified in the absolute maximum ratings. This rating applies to both VS1 and VS2 pins simultaneously and is validated per ISO 7637-2 Pulse 5a. No external TVS diode is required for standard 12 V automotive systems meeting this specification.

How does the device handle simultaneous activation of complementary half-bridge outputs?

The TLE94110ELXUMA1 incorporates hardware-level cross-current protection that detects and disables both high-side and low-side drivers if simultaneous conduction is sensed. This prevents shoot-through current spikes and automatically recovers after the fault condition clears, without requiring MCU intervention or reset.

Can open-load diagnostics be performed while the output is actively driving a load?

Yes - open-load diagnostics operate in ON-state for all high-side and low-side outputs. The device injects a small diagnostic current during active conduction and compares resulting voltage drop against programmable thresholds (selectable for HS1/HS2), enabling real-time wire-break detection without interrupting motor operation.

Is daisy-chaining supported across multiple TLE94110ELXUMA1 devices?

Yes - the SDO pin supports daisy-chain topology: SDO of one device connects to SDI of the next, allowing cascaded SPI status reads using a single CSN line. All devices share common SCLK and CSN, and each returns its 16-bit status word sequentially in one frame, reducing MCU GPIO and timing overhead.
