Product details
Overview
TLE94112ELXUMA1 from Infineon Technologies is a protected 12-channel half-bridge driver IC designed for automotive motion control, specifically HVAC flap DC motor actuation. It features twelve independently diagnosable half-bridge outputs, 16-bit SPI interface with daisy-chain capability, and integrated protections including overcurrent (≥0.9 A), open-load detection (HS/LS), and overtemperature pre-warning. Operates from 5.5–18 V supply with <0.1 µA quiescent current in sleep mode.
For engineers reviewing the TLE94112ELXUMA1 datasheet, TLE94112ELXUMA1 pinout, TLE94112ELXUMA1 application, or TLE94112ELXUMA1 equivalent, key selection criteria include SPI-controlled bidirectional motor drive capability, diagnostic granularity per channel, thermal performance in PG-SSOP-24 package, and compliance with automotive voltage transients up to 40 V load dump.
Technical Context
The device implements twelve independent half-bridge stages, each with programmable PWM (80/100/200 Hz, 8-bit duty cycle) and configurable operation modes: forward, reverse, brake, and high-impedance. All outputs support short-circuit-to-VS/GND detection and cross-current protection via internal current sensing and logic-controlled shutdown.
Diagnosis is centralized through a 16-bit SPI interface supporting in-frame response and global error flag assertion. Open-load detection operates in ON-state for all high-side and low-side outputs, with selectable thresholds for HS1 and HS2 channels. Thermal monitoring includes pre-warning at 150°C and hard shutdown above safe junction limits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Count | 12 independent half-bridge drivers for bidirectional DC motor control |
| Supply Voltage Range | 5.5–18 V normal operation; supports 40 V load dump protection |
| Logic Compatibility | 3.0–5.5 V VDD; 3.3 V / 5 V inputs with hysteresis |
| Overcurrent Threshold | Minimum 0.9 A per channel; enables robust motor stall handling |
| Quiescent Current | 0.1 µA at Tj = 85°C in sleep mode - critical for always-on automotive modules |

| Thermal Package | PG-SSOP-24 with exposed die pad - enables PCB-level heat sinking and EMC improvement |
Pinout & Package
Package: PG-SSOP-24 (24-pin shrink small outline package) with exposed die pad (EP) for thermal and EMC enhancement. EP must be connected to GND or left floating; electrical ground is provided by pins 1, 12, 13, and 24.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND (pins 1,12,13,24) | Power and signal reference ground | Four dedicated ground connections minimize IR drop and improve noise immunity in high-current switching |
| VS1 / VS2 (pins 16,21) | Main power supply for half-bridges | Dual VS pins reduce trace inductance; must be externally shorted for optimal current sharing |
| OUT1–OUT12 (pins 2,3,4,9,10,11,14,15,17,18,22,23) | Half-bridge output terminals | Twelve independent power outputs - each drives one motor winding or relay coil |
| SDI / SDO / SCLK / CSN (pins 5,7,20,19) | SPI serial interface signals | Full-duplex SPI with chip select enables daisy-chaining of multiple TLE94112EL devices |
| EN (pin 8) | Enable input with internal pull-down | Pulling EN low places device in ultra-low-power sleep mode (<0.1 µA) |
| VDD (pin 6) | Logic supply voltage | Separate 3.0–5.5 V rail decouples digital control from noisy power stage |
Key Features
| Feature | Design Value |
|---|---|
| Independent per-channel diagnosis | Each of 12 outputs reports overcurrent, open-load (HS/LS), and temperature fault via SPI status register |
| Selectively configurable open-load threshold | HS1 and HS2 channels support user-defined open-load detection sensitivity for precision motor feedback |
| Global error flag with fast response | Single-pin assertion indicates any active fault condition - enables immediate system-level error handling |
| Load-dump tolerant design | Withstands 40 V transients on VS pins without latch-up or damage - meets ISO 7637-2 Pulse 5a requirements |
| Thermally optimized package | Exposed die pad reduces thermal resistance (RthJA ≈ 50 K/W typical) - sustains continuous 1.8 Ω RDS(on) per side at 150°C |
Applications
| HVAC Flap Actuation | Side Mirror Adjustment |
|---|---|
|
Use Scenario: Precise positioning of HVAC blend and mode flaps in automotive climate control systems. IC Role / Device Role / Timing Role: Twelve half-bridge outputs drive up to six bidirectional DC motors (each motor uses two channels), with PWM-controlled speed and direction. Use Value: Enables closed-loop flap control with real-time open-load detection - prevents jammed-motor failures and ensures air distribution accuracy. |
Use Scenario: X-Y axis movement and fold/unfold functions for power-adjustable exterior mirrors. IC Role / Device Role / Timing Role: Dedicated half-bridge pairs control mirror tilt (X/Y) and folding actuators, with brake mode for position hold. Use Value: Eliminates need for external H-bridges and discrete protection - reduces BOM count and improves ASIL-B functional safety compliance. |
| Monostable/Bistable Relays | LED Load Driving |
|
Use Scenario: Driving monostable (pulse-actuated) and bistable (latching) relays in body control modules. IC Role / Device Role / Timing Role: High-side/low-side outputs deliver precise pulse width and polarity to set/reset relay states. Use Value: Integrated open-load diagnostics confirm relay coil integrity - avoids false "relay stuck" faults during vehicle self-test. |
Use Scenario: Controlling LED arrays in interior lighting, ambient lighting, or status indicators. IC Role / Device Role / Timing Role: Configurable PWM outputs drive LEDs with constant-current behavior using external sense resistors. Use Value: Leverages same diagnostic infrastructure (overcurrent, open-load) used for motors - simplifies firmware validation across load types. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar 12-channel half-bridge driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLE94110ELXUMA1 | 10-channel variant; identical SPI interface, protection, and package | Fewer outputs limit motor count per IC - requires additional driver for 12-motor systems | Select when system uses ≤10 motor loads and board space is constrained |
| TLE94113ELXUMA1 | 12-channel with enhanced ESD rating (±8 kV HBM); otherwise functionally identical | Better suited for high-noise zones (e.g., under-hood, door modules) requiring higher ESD immunity | Choose for new designs targeting ISO 10605 Level 4 or where field return data shows ESD-related failures |
Compared with TLE94110ELXUMA1, TLE94112ELXUMA1 delivers full 12-output capability without daisy-chaining overhead; versus TLE94113ELXUMA1, it offers identical motor control functionality at lower cost where ESD stress is not a primary concern.

FAQ
What is the maximum PWM frequency supported by TLE94112ELXUMA1?
The device supports three fixed PWM frequencies: 80 Hz, 100 Hz, and 200 Hz, each with 8-bit duty cycle resolution (0–255). These frequencies are selected via SPI configuration registers and are optimized for DC motor commutation and relay driving - not for high-speed switching applications like Class-D audio or SMPS.
Does TLE94112ELXUMA1 require external current-sense resistors for overcurrent protection?
No. Overcurrent protection is implemented internally using MOSFET RDS(on) sensing - no external sense resistor is needed. The minimum trip threshold is 0.9 A per channel, and fault detection is reported via SPI status registers and the global error flag.
Can TLE94112ELXUMA1 drive both high-side and low-side configured loads?
Yes. Each of the 12 outputs is a fully independent half-bridge, capable of driving either high-side, low-side, or H-bridge configurations. Open-load diagnostics operate in ON-state for both high-side and low-side outputs, and cross-current protection prevents shoot-through during switching transitions.
Is the exposed die pad (EP) electrically connected to ground internally?
No. The exposed die pad is not internally connected to any electrical node. It serves only for thermal conduction and EMC shielding. For optimal performance, Infineon recommends connecting EP to PCB ground plane - but it must not be used as the sole ground path, as electrical grounding is provided exclusively by pins 1, 12, 13, and 24.
