Specifications
TLE9104SHXUMA1 is Infineon’s AEC-Q100 qualified smart quad-channel low-side powertrain driver IC built with Smart Power Technology (SPT). The suffix XUMA1 stands for tape-and-reel, lead-free, halogen-free PG-DSO-20 SMD packaging. It integrates four open-drain DMOS power stages with comprehensive load diagnostics and multi-mode control interfaces, dedicated for automotive powertrain, transmission and high-reliability industrial actuator drive systems.
👉 It differs from low-current body control switch ICs (TLE8xxx series) without high inductive load clamping capability. This powertrain-grade device supports up to 5A peak per channel, 50–60V integrated avalanche clamping for fuel injectors and heavy solenoids, with full SPI-based fault reporting for safety-critical ECUsInfineon Technologies.
Key Features
- Four Independent Low-Side DMOS Output Channels
- 4 open-drain output stages, typical Rds(on) = 300 mΩ @ 150°C
- Per-channel max continuous load: 3 A; configurable peak current limit up to 5 A via SPI register
- Channels 1+2 / 3+4 support parallel connection to double drive capacity for high-current actuators
- Integrated active voltage clamp (Vds(cl) = 50~60 V) to absorb inductive flyback energy from injectors and solenoids
- Max turn-on / turn-off time: 15 µs, stable for high-frequency PWM injection control
- Dual Control Interfaces (Parallel Logic Input + 16-bit SPI)
- Direct parallel digital input pins for fast real-time PWM drive from MCU without SPI latency
- 8 MHz 16-bit SPI bus for channel enable configuration, parameter setup and full fault diagnostic readback
- Separate VIO signal supply (3.0 V ~ 5.5 V), compatible with 3.3 V automotive MCU cores
- Global EN safety enable pin to cut all outputs in system fault conditions
- Full Per-Channel Integrated Protection & Diagnostics
- Configurable over-current (OC) shutdown with SPI adjustable threshold
- Overtemperature (OT) thermal shutdown with independent thermal filtering
- Open-load detection (OL) for disconnected injector/solenoid wiring diagnosis
- Short-circuit-to-GND (SCG) detection and automatic channel latch-off
- Global fault flag output pin to notify host MCU of any channel failure
- ESD protection on all logic and power pins for harsh automotive EMC environments
- Electrical & Thermal Ratings
- Main supply VDD range: 4.5 V ~ 5.5 V automotive battery logic rail
- Operating junction temperature: -40 °C ~ +150 °C (automotive grade)
- Heatslug-down exposed thermal pad for enhanced PCB heat dissipation
