Product details
Overview
TLE9183QKXUMA1 from Infineon is a high-voltage 3-phase bridge driver IC designed to control six external N-channel MOSFETs in automotive inverter applications. It operates across 5.5 V–40 V supply, supports 0–100% duty cycle, delivers phase voltage feedback with SPI-programmable thresholds, and integrates three current sense amplifiers for shunt-based motor current measurement - enabling precise torque control in electric power steering (EPS) systems.
For engineers reviewing the TLE9183QKXUMA1 datasheet, TLE9183QKXUMA1 pinout, TLE9183QKXUMA1 application, or TLE9183QKXUMA1 equivalent, key selection considerations include ASIL-D compliance per ISO 26262, dual independent disable paths (SOFF/ENA), -15 V to 40 V motor pin robustness, secure SPI with CRC, and functional redundancy in supervision and current sensing.
Technical Context
The TLE9183QKXUMA1 implements a floating high-side driver architecture supporting 12 V battery systems with up to 40 V absolute max ratings on bridge pins and -15 V tolerance on motor terminals. Its integrated charge pump enables gate drive for high-side N-FETs without external bootstrap components.
Supervision functions include monitoring of Vs, VDHP, VCC, internal CLK, and high-side buffer capacitor voltages - all configurable via SPI with adjustable thresholds and filter times. Diagnostic coverage is enhanced by functional-redundant current sense amplifiers, phase feedback comparators, and a window watchdog for µC supervision.

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | IO Supply Input | Provides 3.3 V logic supply for digital circuitry; tolerant down to 3 V for compatibility with low-voltage µCs. |
| VCC | µC Supply Monitoring Input | Monitors microcontroller supply rail; triggers fault if outside programmable window (e.g., 4.5 V–5.5 V). |
| SOFF | Fast Disable Input | Functional-independent hardware shutdown path - forces all outputs off within <1 µs regardless of SPI state. |

| SHU/SHV/SHW | High-Side Driver Outputs | Floating gate drivers for upper-leg N-FETs; each includes shoot-through protection and dead-time generation. |
| SLU/SLV/SLW | Low-Side Driver Outputs | Ground-referenced gate drivers for lower-leg N-FETs; synchronized with SHx outputs for complementary PWM. |
| ISU/ISV/ISW | Current Sense Amplifier Inputs | Differential inputs for shunt resistors; support -10 V transient tolerance and SPI-adjustable gain/offset calibration. |
| PFU/PFV/PFW | Phase Feedback Inputs | Analog inputs for phase voltage sensing; thresholds programmable via SPI to detect overvoltage or undervoltage conditions. |
Key Features
| Feature | Design Value |
|---|---|
| Limp-home functionality | SPI-configurable failure response - allows controlled transition to safe operating state (e.g., coasting or braking) upon detected fault. |
| Reverse diode measurement | Enables FET junction temperature estimation using body diode forward voltage - eliminates need for external thermistors in motor modules. |
| Passive clamping of external FETs | Internal clamp circuits limit dv/dt-induced shoot-through risk during fast switching - improves reliability in high-di/dt EPS inverters. |
| Functional redundant disable paths | Dual independent hardware disable (SOFF + ENA) - satisfies ASIL-D requirement for fault-tolerant shutdown without single-point failure. |
| Secure SPI with CRC | Hardware CRC over both address and data fields - prevents misconfiguration due to EMI-induced bit flips in safety-critical communication. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 3-phase gate driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STGD18N40LZ | Discrete high-side/low-side driver pair - no integrated current sensing, SPI, or ASIL-D certification. | Targeted at cost-sensitive industrial inverters; lacks automotive qualification and functional safety features. | Choose only for non-safety-critical 24 V systems where BOM count reduction outweighs diagnostic capability loss. |
| DRV3205-Q1 | TI 3-phase driver with integrated current sense but no reverse diode measurement or limp-home SPI configurability. | Supports ASIL-B only; missing dedicated high-voltage supervision registers and charge pump monitoring. | Select when system-level ASIL-D decomposition permits driver-level ASIL-B with host MCU handling higher-level diagnostics. |
Compared with STGD18N40LZ and DRV3205-Q1, the TLE9183QKXUMA1 uniquely combines ASIL-D certification, reverse diode temperature sensing, and SPI-configurable limp-home behavior - making it the only option for EPS systems requiring full hardware-level fault containment without software intervention.

FAQ
What is the maximum allowable voltage on the SHx pins?
The SHU, SHV, and SHW pins support an absolute maximum voltage of 40 V and tolerate negative transients down to -15 V. This rating applies under all operating and fault conditions, including load dump and inductive flyback, and is verified per AEC-Q100 stress testing protocols.
Does the TLE9183QKXUMA1 require external bootstrap capacitors?
No. The device integrates a charge pump circuit that generates the high-side gate drive voltage internally, eliminating the need for external bootstrap diodes and capacitors. This simplifies PCB layout and improves reliability in high-vibration automotive environments.
How is current sensing calibrated on the TLE9183QKXUMA1?
Zero-current offset calibration is performed via SPI command sequence that activates internal test currents and measures resulting amplifier output. Gain is adjusted digitally through SPI registers, and calibration data is stored in non-volatile memory for retention across power cycles.
Can the TLE9183QKXUMA1 operate with a 3.3 V microcontroller?
Yes. Its digital I/Os are TTL- and 3.3 V µC-compatible, with guaranteed logic high recognition down to 2.0 V and logic low acceptance up to 0.8 V. The VDD pin accepts 3.3 V ±10 %, and all SPI signals meet standard CMOS timing margins at this supply.
