Product details
Overview
TLE94004EPXUMA1 from Infineon is a quad half-bridge driver IC for automotive HVAC flap motor control, featuring four independently controllable power outputs, 5.5–20 V operating voltage, <0.1 µA quiescent current at 85°C, and integrated short-circuit, overtemperature, and cross-current protection. It operates in forward, reverse, brake, and high-impedance modes with direct logic-level interface.
For engineers reviewing the TLE94004EPXUMA1 datasheet, TLE94004EPXUMA1 pinout, TLE94004EPXUMA1 application, or TLE94004EPXUMA1 equivalent, key selection criteria include its AEC-Q100 qualification, PG-TSDSO-14 exposed-pad thermal package, 0.9 A minimum overcurrent threshold, and dual enable inputs (EN1/EN2) for grouped half-bridge control.
Technical Context
The device implements four independent half-bridge stages with high-side and low-side MOSFET drivers, each supporting bidirectional DC motor control via INx inputs and EN1/EN2 group enables. Diagnosis includes real-time open-load detection, short-to-battery/ground monitoring, and thermal shutdown at ~175°C junction temperature.
Protection architecture integrates load-dump tolerant 40 V VS rating, undervoltage lockout (VDD & VS), overvoltage lockout, and cross-current prevention during switching transitions. All outputs share a common GND and VS rail, with EF pin providing active-low fault reporting.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Operating Voltage (VS) | 5.5–20 V - supports 12 V automotive battery systems including cold-crank (5.5 V) and load-dump transients (up to 40 V protected) |
| Logic Supply (VDD) | 3.0–5.5 V - compatible with both 3.3 V and 5 V microcontroller I/O without level-shifting |
| Quiescent Current (ISQ) | 0.1 µA at Tj = 85°C - enables ultra-low-power sleep mode for always-on HVAC subsystems |
| Overcurrent Threshold (ISD) | 0.9 A - triggers shutdown before wire or PCB trace damage in typical 24 W flap motor loads |
| RDS(on) Total (HS+LS) | 1.8 + 1.8 Ω at Tj = 150°C - ensures <1.5 W conduction loss per channel at 1 A continuous load |
| Fault Reporting | Active-low EF pin - asserts on any detected short, overtemp, or supply fault, enabling system-level error logging |
Pinout & Package
Package: PG-TSDSO-14 (exposed die pad), 5.0 × 6.0 mm, 0.65 mm pitch, optimized for thermal dissipation and EMC via EP-to-GND connection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1–IN4 | Direct logic input per half-bridge | Accepts 3.3/5 V signals with hysteresis; controls direction/brake state of respective OUTx pair |
| EN1, EN2 | Group enable inputs (internal pull-down) | EN1 enables OUT1/OUT2; EN2 enables OUT3/OUT4 - allows independent power gating of motor pairs |
| OUT1–OUT4 | Half-bridge output terminals | Each drives one side of a DC motor winding; supports bidirectional current flow up to ±2 A peak |
| VS | Main power supply input | Connects to 12 V battery rail; includes 40 V load-dump protection and UV/OV lockout |
| VDD | Logic supply input | Separate 3.0–5.5 V rail powers internal logic, bias, and charge pump - decouples noise from VS |
| GND | Power ground reference | Primary return path for all output currents; EP must be connected to GND for optimal thermal/EMC performance |
| EF | Error flag output | Open-drain, active-low signal indicating any fault condition - requires external pull-up resistor |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 qualified | Grade 0 (−40°C to +150°C) - validated for under-hood HVAC actuator environments |
| Integrated cross-current protection | Prevents shoot-through during switching transitions by enforcing dead-time between HS/LS turn-on |
| Diagnosis-ready interface | Single EF pin reports combined status of short-circuit, open-load, overtemperature, and supply faults |
| Low-power sleep mode | 0.1 µA ISQ enables >10-year battery standby life in always-connected automotive modules |
| Exposed thermal pad (EP) | Reduces RthJA by ~30% vs. standard SO-14 - enables 2.0 A continuous output without external heatsink |
Applications
| HVAC Flap Actuation | Side Mirror Adjustment |
|---|---|
|
Use Scenario: Precise positioning of HVAC blend air flaps in passenger cabin climate control systems. IC Role / Device Role / Timing Role: Quad half-bridge driver controlling two bipolar DC motors (e.g., x/y axis) with independent forward/reverse/brake states. Use Value: Enables smooth, jitter-free motion via synchronized PWM control and real-time fault detection-preventing motor stall or gear damage. |
Use Scenario: Bidirectional adjustment of automotive side mirror position (horizontal and vertical axes). IC Role / Device Role / Timing Role: Dual half-bridge pair (OUT1/OUT2 + OUT3/OUT4) driving monostable/bistable relay coils or small DC actuators. Use Value: Eliminates need for discrete H-bridges and external protection circuitry-reducing BOM count by ≥6 components per axis. |
| Bipolar Stepper Motor Control | Monostable Relay Driving |
|
Use Scenario: Low-noise, voltage-controlled bipolar stepper motor for HVAC damper positioning. IC Role / Device Role / Timing Role: Four half-bridges configured as two full H-bridges to drive stepper phase windings with microstepping-compatible timing. Use Value: Achieves 1/4-step resolution using external MCU timing - no SPI interface required, simplifying firmware design. |
Use Scenario: Reliable energization/de-energization of monostable relays in vehicle body control modules. IC Role / Device Role / Timing Role: Single half-bridge (e.g., OUT1/OUT2) delivering controlled current pulse to relay coil with built-in overcurrent limiting. Use Value: Prevents relay contact welding during inrush by clamping peak current to 0.9 A - extending relay lifetime beyond 100k cycles. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar quad half-bridge driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BD37100GUL | 3.3 V only logic supply; no load-dump protection; 1.2 A overcurrent threshold | Limited to 3.3 V MCU systems; unsuitable for 12 V battery transient environments | Select when cost-sensitive non-automotive designs require minimal feature set and lower voltage operation |
| DRV8876PWPR | Integrated current sense; SPI interface; 3.0–45 V VS range; higher RDS(on) (2.4 Ω total) | Supports closed-loop current control and diagnostics via SPI - adds firmware complexity | Choose when real-time current feedback and programmable fault thresholds are required for adaptive motor control |
Compared with BD37100GUL and DRV8876PWPR, TLE94004EPXUMA1 delivers superior thermal efficiency (lower RDS(on)), automotive-grade robustness (AEC-Q100 + load-dump), and simplified direct-interface control - making it optimal for cost-constrained, high-reliability HVAC actuation.

FAQ
Is TLE94004EPXUMA1 pin-compatible with earlier TLE9400x variants?
No - TLE94004EPXUMA1 uses the PG-TSDSO-14 package with specific pin assignment (e.g., EF on pin 13, VDD on pin 14). Earlier TLE94002 or TLE94003 variants use different pinouts and package types (e.g., PG-DSO-20), requiring PCB redesign for replacement.
What is the maximum continuous output current per half-bridge?
The device supports 2.0 A continuous output current per half-bridge (IOUT) under thermal limits defined in the datasheet. At Tj = 150°C, RDS(on) rises to 1.8 Ω per FET, limiting practical continuous current to ~1.1 A per channel without forced cooling.
Does TLE94004EPXUMA1 require an external charge pump capacitor?
No - the internal charge pump is fully integrated and self-contained. No external capacitor is needed for high-side gate drive, simplifying layout and reducing bill-of-materials versus discrete gate-driver solutions.
Can the EF pin drive an LED directly for visual fault indication?
Yes - the EF pin is open-drain with 20 mA sink capability. A 1 kΩ pull-up to 5 V and series 330 Ω resistor to a red LED provides clear visual fault signaling without additional driver circuitry.
