Product details
Overview
TLE94104EPXUMA1 from Infineon is a quad half-bridge driver IC for automotive motion control, integrating four independently controllable high-side/low-side power stages with SPI interface, 0.9 A minimum overcurrent threshold, 1.8 Ω total RDS(on) per half-bridge at 150°C, and <0.1 µA quiescent current in sleep mode-used in HVAC flap actuation.
For engineers reviewing the TLE94104EPXUMA1 datasheet, TLE94104EPXUMA1 pinout, TLE94104EPXUMA1 application, or TLE94104EPXUMA1 equivalent, this page delivers verified electrical parameters, thermal performance data, SPI diagnostic behavior, and automotive-grade protection features required for motor control BOM validation.
Technical Context
The device implements four independent half-bridge power stages with integrated charge pump, cross-current protection, and real-time open-load diagnostics in both ON-state (high-side and low-side) and OFF-state. Each output supports forward, reverse, brake, and high-impedance modes via 16-bit SPI commands.
Its protection architecture includes short-circuit detection to battery or ground, overtemperature pre-warning and shutdown, VS undervoltage/overvoltage lockout up to 40 V load dump, and daisy-chain-capable SPI with in-frame response for multi-device systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output count | 4 independent half-bridge drivers for bidirectional DC motor control |
| VS operating range | 5.5–20 V supply; withstands 40 V load dump for automotive robustness |
| RDS(on) (HS+LS) | 1.8 + 1.8 Ω max at Tj = 150°C - defines conduction loss and thermal derating |
| Overcurrent threshold | ≥0.9 A - enables reliable motor stall detection without external sensing |
| SPI clock frequency | Up to 5 MHz - supports fast configuration and real-time status polling |
| Quiescent current | 0.1 µA typical at 85°C - meets automotive sleep-mode current budgets |
| Logic compatibility | 3.0–5.5 V VDD; 3.3 V / 5 V tolerant inputs with hysteresis - simplifies MCU interface |
Pinout & Package
Package: PG-TSDSO-14 (exposed die pad), fine-pitch SOIC variant optimized for thermal dissipation and PCB space efficiency in automotive modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (SDI) | Serial data input | CMOS input with internal pull-down; receives 16-bit SPI command frames |
| 2 (CSN) | Chip select not | Active-low enable for SPI communication; internal pull-up ensures safe default state |
| 3 (SCLK) | Serial clock input | Drives synchronous SPI timing up to 5 MHz; internal pull-down prevents floating |
| 5 (VS) | Main power supply | Connects to battery rail (5.5–20 V); handles 40 V transients during load dump |
| 6–7, 9–10 (OUT1–OUT4) | Half-bridge outputs | Four independent power terminals driving DC motors or relays; each supports H-bridge operation |
| 8 (GND) | Power ground | Primary return path for all output currents; EDP must be connected to GND for optimal EMC/thermal performance |
| 11 (EN) | Enable input | Pull-low to enter standby mode; internal pull-down ensures default disable on power-up |
| 13 (SDO) | Serial data output | Drives daisy-chained SDO of next device or provides in-frame response during readback |
| 14 (VDD) | Logic supply | 3.0–5.5 V supply for internal logic and SPI interface; decoupling capacitor required |
Key Features
| Feature | Design Value |
|---|---|
| Daisy-chain SPI interface | Enables control and diagnosis of multiple TLE94104EPXUMA1 devices using single MCU SPI port |
| Open-load diagnostics in ON-state | Verifies continuity of both high-side and low-side paths while actively driving - critical for safety-critical HVAC actuators |
| Global error flag | Single-pin indication of any fault (overcurrent, overtemperature, open load, UV/OV) - reduces MCU polling overhead |
| Cross-current protection | Prevents shoot-through by detecting simultaneous high-side/low-side conduction before damage occurs |
| Thermal pre-warning | Generates early warning flag before junction temperature reaches 150°C shutdown threshold - enables graceful system response |
Applications
| HVAC Flap Actuation | Side Mirror X-Y Adjustment |
|---|---|
|
Use Scenario: Precise positioning of HVAC air flaps in vehicle cabin climate control systems. IC Role / Device Role / Timing Role: Quad half-bridge driver executing bidirectional motor control sequences (forward/reverse/brake) via SPI commands. Use Value: Integrated open-load and overcurrent diagnostics eliminate need for external sense resistors, reducing BOM cost and board area. |
Use Scenario: Independent horizontal and vertical adjustment of electric side mirrors. IC Role / Device Role / Timing Role: Dual half-bridge pairs drive two separate DC motors with synchronized direction and braking control. Use Value: Sleep-mode quiescent current <0.1 µA meets automotive off-battery leakage requirements without external power gating. |
| Bistable Relay Control | Voltage-Controlled Bipolar Stepper Motor |
|
Use Scenario: Driving monostable and bistable relays in body control modules. IC Role / Device Role / Timing Role: Half-bridge outputs provide timed pulse-width-controlled coil energization for relay latching/unlatching. Use Value: Overvoltage lockout up to 40 V protects against load-dump transients common in 12 V automotive systems. |
Use Scenario: Microstepping-capable bipolar stepper motor control for precision cabin actuators. IC Role / Device Role / Timing Role: Two half-bridges per phase deliver controlled current polarity reversal with fast switching (<5 MHz SPI). Use Value: Cross-current protection prevents destructive shoot-through during phase commutation transitions. |
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 |
|---|---|---|---|
| BD37100FV-M | 3.3 V only logic supply; no daisy-chain SPI; analog PWM input instead of digital SPI control | Lacks integrated diagnostics and requires external current sensing for overload detection | Preferred where simple PWM interface suffices and diagnostic depth is secondary |
| DRV8876PWPR | Two-channel H-bridge; higher RDS(on) (2.4 Ω HS+LS); no open-load diagnostics in ON-state | Requires dual ICs for four-output functionality; lacks global error flag and thermal pre-warning | Selected when cost-per-channel is prioritized over diagnostic completeness and integration density |
Compared with BD37100FV-M and DRV8876PWPR, TLE94104EPXUMA1 offers superior diagnostic coverage (ON-state open-load, cross-current, thermal pre-warning), tighter thermal resistance via exposed pad, and single-chip quad control - making it optimal for ASIL-B-aligned HVAC and mirror systems requiring functional safety awareness.

FAQ
What is the maximum allowable VS voltage during load dump conditions?
The TLE94104EPXUMA1 is rated for VS(LD) = 40 V under load dump conditions per ISO 7637-2 Pulse 5a, enabling direct connection to automotive battery rails without external TVS clamping. This rating is validated across -40°C to +150°C junction temperature range and applies to both powered and unpowered states.
How does open-load diagnosis work in ON-state for high-side and low-side outputs?
During active drive, the device injects a small diagnostic current into each output path and measures resulting voltage drop to detect open circuits - separately for high-side (between VS and OUT) and low-side (between OUT and GND). This occurs without interrupting motor operation and is reported via dedicated status bits in the SPI status register.
Can TLE94104EPXUMA1 drive a bipolar stepper motor without external current regulation?
No - while the device supports bipolar stepper phasing via its four half-bridges, it lacks integrated current regulation or chopper control. External current-sense resistors and MCU-based PWM duty-cycle adjustment are required to maintain phase current within the 0.9 A minimum overcurrent threshold and prevent thermal runaway.
Is the exposed die pad (EP) electrically connected to GND internally?
No - the exposed die pad is thermally and electrically isolated from internal circuitry. It must be externally connected to PCB GND plane for optimal thermal dissipation and EMC performance, but it serves no internal grounding function. Pin 8 remains the sole electrical GND reference for output current return paths.
