Product details
Overview
TLE6270RAUMA1 from Infineon Technologies is a quad-channel automotive low-side injector driver IC designed for gasoline direct injection (GDI) systems. It integrates four 80 V, 11.5 A peak current low-side power switches with programmable peak/hold current control (IP_C = 11.5 A typ., IH = 2.3 A typ.), SPI-based diagnostics, and high-side transistor control logic. Used in engine control units to drive fuel injectors via external high-side switches.
For engineers reviewing the TLE6270RAUMA1 datasheet, TLE6270RAUMA1 pinout, TLE6270RAUMA1 application, or TLE6270RAUMA1 equivalent, key selection criteria include channel count, clamping voltage (87 V typ.), on-resistance (≤300 mΩ at 150 °C), diagnostic register access via SPI, and AEC-Q100 qualification for under-hood deployment.
Technical Context
The TLE6270RAUMA1 implements dual independent output groups (A/B), each with four dedicated low-side drivers and associated control outputs (NCTL2A/NCTL3A etc.) for external high-side transistors. It uses an internal oscillator or external resonator (OSC1/OSC2 pins) to synchronize timing-critical injector actuation sequences.
Diagnostic functionality includes open-load detection in OFF state, overvoltage protection, and failure reporting via 16-bit SPI-accessible Failure Register and Output/Input Coders. Protection features cover short-circuit, ESD, overtemperature, and undervoltage reset - all operating within automotive ambient temperature range (−40 °C to +150 °C junction).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output channels | 4 independent low-side driver channels, grouped as Bank A and Bank B for synchronized injector control. |
| Max continuous output voltage | 80 V - supports battery-supplied GDI systems with transient clamping up to 87 V. |
| Peak output current | 11.5 A typ. - enables fast injector opening during cold-start conditions. |
| Hold current | 2.3 A typ. - sustains injector open state with reduced power dissipation after initial peak. |
| On-resistance (max) | 300 mΩ at 150 °C - ensures thermal robustness during sustained operation in engine bay environments. |
| Clamping voltage | 87 V typ. - suppresses inductive kickback from injector coils without external TVS diodes. |
| Interface | SPI (CLK, SDI, SDO, NCS) - enables real-time fault logging, configuration, and diagnostics in ECU firmware. |
Pinout & Package
Package: PG-DSO-36 (36-pin exposed-pad SOIC), RoHS-compliant, AEC-Q100 qualified, with integrated thermal pad for enhanced heat dissipation in high-power automotive applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC (Pin 7) | 5 V logic supply input | Powers internal logic, SPI interface, and diagnostic circuitry; decoupling required near pin. |
| LP_GND (Pin 10) | Low-power ground reference | Isolates digital/analog ground paths to reduce noise coupling into SPI and oscillator circuits. |
| GND (Pins 1, 18, 19, 36) | High-power ground return | Provides low-inductance path for 11.5 A peak currents; must be connected to thermal pad and chassis ground. |
| OUT1A/OUT1B/OUT4A/OUT4B (Pins 2–3, 16–17, 34–35, 20–21) | Low-side driver outputs | Each pair drives one injector channel; dual-pin layout reduces trace inductance and improves EMI performance. |
| NON1A/NON1B/NON4A/NON4B (Pins 30, 15, 33, 22) | Active-low enable inputs | Directly control driver activation timing; compatible with standard microcontroller GPIOs. |
| NCTL2A/NCTL3A/NCTL2B/NCTL3B (Pins 5–6, 14–13) | High-side transistor control outputs | Drive external high-side switches (e.g., P-channel MOSFETs) to supply boosted voltage to injectors. |
| HS_DiagA/HS_DiagB (Pins 31, 24) | High-side diagnostic feedback inputs | Monitor status of external high-side switches for open-circuit or short-to-battery faults. |
| Pgr_IP / Pgr_IH / Pgr_IPC (Pins 9, 4, 8) | Current programming inputs | Analog resistor-programmable pins setting peak current (IP), hold current (IH), and peak current clamp (IPC). |
| OSC1/OSC2 (Pins 11–12) | External resonator interface | Supports precise timing for injector pulse-width modulation; OSC2 must be tied to GND if internal oscillator used. |
| SDI/SDO/CLK/NCS/NRES (Pins 27, 26, 28, 29, 25) | SPI interface and reset | Enable full read/write access to diagnostic registers, configuration bits, and fault flags via standard SPI protocol. |
Key Features
| Feature | Design Value |
|---|---|
| Programmable peak/hold current control | Resistor-adjustable IP (up to 11.5 A), IH (2.3 A), and IPC thresholds ensure optimal injector response across fuel types and temperatures. |
| Dual bank architecture with independent diagnostics | Separate failure detection per group (A/B) enables granular fault isolation in multi-cylinder engines without cross-bank interference. |
| Open-load detection in OFF state | Identifies disconnected or broken injector wiring before engine start - critical for OBD-II compliance and fail-safe operation. |
| Integrated overvoltage clamping (87 V) | Eliminates need for external TVS diodes across injector coils, reducing BOM count and PCB area in space-constrained ECUs. |
| AEC-Q100 Grade 0 qualification | Rated for junction temperatures up to +150 °C - validated for under-hood placement in modern turbocharged GDI powertrains. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad low-side injector driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BTS724G | Single-channel, 60 V max, no integrated SPI diagnostics; requires external MCU polling for fault status. | Lacks multi-channel synchronization and bank-level diagnostics - suitable only for non-OBD-II or legacy single-injector modules. | Select when cost sensitivity outweighs diagnostic depth and channel integration requirements. |
| TPIC2603D | Quad-channel, 40 V max, no high-side control outputs or pre-charge logic; limited to low-voltage port fuel injection. | Cannot support boosted injector voltages (>40 V) or coordinated high-side switching - incompatible with GDI architectures. | Consider only for throttle-body or manifold injection systems operating below 36 V battery nominal. |
Compared with BTS724G and TPIC2603D, the TLE6270RAUMA1 uniquely combines quad-channel 80 V capability, SPI-accessible diagnostics, and integrated high-side control outputs - making it the only drop-in solution for AEC-Q100-compliant GDI ECUs requiring OBD-II readiness and thermal resilience above 125 °C.

FAQ
What is the maximum junction temperature rating for TLE6270RAUMA1?
The TLE6270RAUMA1 is qualified per AEC-Q100 Grade 0 with a maximum junction temperature of +150 °C. This rating is validated through accelerated life testing and thermal cycling across −40 °C to +150 °C ambient, ensuring reliability in under-hood ECU placements near turbochargers or exhaust manifolds.
Does TLE6270RAUMA1 require an external clock source?
No - the device includes an internal oscillator but also supports optional external resonator connection via OSC1/OSC2 pins (1–2 MHz typical). External timing is recommended when precise synchronization with other ECU peripherals (e.g., ADC sampling) is required; internal oscillator suffices for standalone injector control.
How does the open-load detection function work during injector OFF state?
During OFF state, the TLE6270RAUMA1 applies a small diagnostic current (~1 mA) through the output channel and monitors voltage at the OUTx pin. If voltage exceeds threshold (indicating open circuit), the fault is latched into the Failure Register and reported via SPI bit OLn (Open Load n) without disrupting normal operation.
Can TLE6270RAUMA1 drive injectors directly without external high-side switches?
No - the TLE6270RAUMA1 is a low-side driver only. It controls the ground path of the injector coil while relying on external high-side switches (e.g., P-channel MOSFETs driven by NCTL2A/NCTL3A outputs) to apply boosted voltage (e.g., 60–80 V) for fast injector opening. Direct coil driving would exceed its 80 V rating.
