Product details
Overview
TLE7183FXUMB1 from Infineon Technologies is a 3-phase high- and low-side MOSFET gate driver IC for automotive motor control, featuring six independent gate outputs (3×HS/3×LS), integrated charge pumps enabling operation down to 5.5 V supply, 30 kHz PWM capability, short-circuit protection with five selectable detection thresholds, and shunt-based current sensing with op-amp output VO. It drives external N-channel MOSFETs in electric power steering and water pump inverters.
For engineers reviewing the TLE7183FXUMB1 datasheet, TLE7183FXUMB1 pinout, TLE7183FXUMB1 application, or TLE7183FXUMB1 equivalent, key selection criteria include gate drive strength for 400 nC MOSFETs, dead-time programmability via DT pin, phase voltage feedback (U_fb/V_fb/W_fb), diagnostic ERR1/ERR2 signaling, and AEC-Q100 qualification for 12 V automotive power nets.
Technical Context
The TLE7183FXUMB1 integrates three floating high-side drivers with level shifters and three low-side drivers, each with shoot-through protection and programmable dead time. Its dual charge pump architecture (CH1/CL1 and CH2/CL2) sustains full gate drive performance at VS ≥ 5.5 V, critical for cold-crank conditions.
It embeds analog signal conditioning: a differential current sense amplifier (ISP/ISN → VO), bias reference buffer (VRI/VRO), overcurrent threshold input (VTHOC), and digital phase voltage feedback (U_fb/V_fb/W_fb) for closed-loop motor control. Diagnostic logic monitors undervoltage, overvoltage, overtemperature, and short circuits independently per channel.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 5.5 V to 45 V - supports full functionality during automotive cold-crank (≥5.5 V) and load-dump transients (≤45 V). |
| Gate Drive Output Rise/Fall Time | ≈150 ns - enables fast switching of MOSFETs with up to 400 nC gate charge, minimizing conduction losses. |
| PWM Frequency Support | Up to 30 kHz - suitable for high-efficiency field-oriented control (FOC) in EPS and HVAC blower applications. |
| Short-Circuit Detection Levels | 5 fixed thresholds - configurable via part variant (SCD1–SCD5), allowing precise fault sensitivity tuning per motor phase. |
| Current Sense Amplifier Gain | Fixed gain with ISP/ISN inputs and buffered VO output - provides rail-to-rail analog current representation for ADC interfacing. |
| Phase Voltage Feedback | Digital logic-level U_fb/V_fb/W_fb signals - deliver sampled high-side drain voltage status for commutation timing without external comparators. |
| AEC-Q100 Qualification | Grade 0 (−40 °C to +150 °C junction) - validated for under-hood automotive environments including engine bay placement. |
Pinout & Package
Package: PG-VQFN-48 (7 mm × 7 mm, 0.5 mm pitch) with exposed thermal pad for enhanced heat dissipation in high-power motor drive PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GH1–GH3, GL1–GL3 | Gate drive outputs | Direct connection to MOSFET gates; GHx drive high-side switches, GLx drive low-side switches with integrated shoot-through protection. |
| SH1–SH3, SL1–SL3 | Source monitoring terminals | SHx connect to high-side MOSFET source (phase node); SLx connect to low-side MOSFET source (ground return) for accurate current sensing and short-circuit detection. |
| IH1–IH3, IL1–IL3 | Control inputs | IHx (active-low) and ILx (active-high) accept TTL-compatible logic to independently enable each half-bridge leg. |
| U_fb, V_fb, W_fb | Digital phase feedback | Logic-high when respective high-side MOSFET drain voltage exceeds internal threshold - used for sensorless commutation timing. |
| VO, ISP, ISN, VTHOC | Shunt signal interface | VO = amplified shunt voltage output; ISP/ISN = differential inputs; VTHOC sets overcurrent trip point - enables precise, temperature-stable current monitoring. |
| DT, INH, ENA1, ENA2 | Configuration & control | DT programs dead time; INH globally disables all outputs; ENA1/ENA2 enable groups of drivers - supports functional safety partitioning. |
| ERR1, ERR2 | Fault reporting | Open-drain error flags indicating aggregated faults (ERR1) and overtemperature/overvoltage (ERR2) - simplifies microcontroller interrupt handling. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated dual charge pumps | Enables robust high-side gate drive at VS as low as 5.5 V - eliminates need for external bootstrap diodes/capacitors in 12 V systems. |
| Programmable dead time | Adjustable via external resistor on DT pin - prevents shoot-through during switching transitions without firmware overhead. |
| Five short-circuit detection options | Factory-set thresholds (SCD1–SCD5) - allows matching fault sensitivity to motor winding resistance and cable impedance. |
| Digital phase voltage feedback | U_fb/V_fb/W_fb provide real-time high-side drain status - enables sensorless trapezoidal commutation without Hall sensors or back-EMF filtering. |
| Separate analog ground (AGND) | Isolates current-sense amplifier from noisy digital/power grounds - maintains <1% gain error in shunt measurement accuracy. |
| Sleep mode & disable function | Reduces quiescent current to <100 µA - meets automotive standby power requirements for always-on modules like EPS ECUs. |
Applications
| Electric Power Steering (EPS) | Automotive Water Pump |
|---|---|

| Electro-Hydraulic Brake (EHB) | Cooling Fan Actuator |
|
Use Scenario: Redundant motor actuation in brake-by-wire systems requiring dual independent fault channels and functional safety support. IC Role / Device Role / Timing Role: Dual-enable (ENA1/ENA2) and dual-error (ERR1/ERR2) architecture supports hardware-level redundancy for ISO 26262 ASIL-D decomposition.

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-voltage N-channel MOSFET (400 V, 18 A), not an integrated driver IC. | Requires external gate driver, level shifter, and protection circuitry - increases design complexity and footprint. | Select only if system requires >400 V blocking voltage or discrete layout flexibility; not a functional replacement. |
| DRV3205-Q1 | TI 3-phase driver with integrated current sense ADC (12-bit), no external shunt op-amp needed; lacks VQFN-48 package and phase feedback pins (U_fb/V_fb/W_fb). | Better for systems prioritizing digital current readback over sensorless commutation; unsuitable where phase voltage logic feedback is required. | Choose DRV3205-Q1 for simplified current monitoring; retain TLE7183FXUMB1 when U_fb/V_fb/W_fb timing or analog VO interface is mandatory. |
Compared with STGD18N40LZ (a discrete FET) and DRV3205-Q1 (a digital-current-focused driver), TLE7183FXUMB1 uniquely delivers analog shunt amplification + digital phase feedback + five-tier short-circuit detection in a single AEC-Q100-qualified VQFN package - essential for sensorless EPS and EHB designs requiring deterministic timing and multi-level diagnostics.

FAQ
What is the purpose of the VTHOC pin on the TLE7183FXUMB1?
The VTHOC pin sets the overcurrent detection threshold voltage for the integrated current sense amplifier. Applying a precise DC voltage (typically 0.1 V to 1.0 V) determines the shunt-based current trip point - enabling calibration to match motor phase resistance and desired fault sensitivity without changing hardware.
How does the TLE7183FXUMB1 handle low-supply conditions below 12 V?
It uses two independent integrated charge pumps (CH1/CL1 and CH2/CL2) to generate boosted gate drive voltages, sustaining full high-side drive capability down to VS = 5.5 V. This ensures reliable MOSFET turn-on during automotive cold-crank events without external boost circuitry.
Can the TLE7183FXUMB1 drive both N-channel and P-channel high-side MOSFETs?
No - it is designed exclusively for N-channel high-side MOSFETs, using floating driver stages with level shifters and charge pumps. P-channel devices are incompatible due to lack of complementary drive architecture and undefined behavior with the SHx/VDH sensing topology.
What diagnostic functions are reported separately on ERR1 and ERR2 pins?
ERR1 signals aggregated faults: short circuit, overcurrent, and undervoltage shutdown. ERR2 reports system-level anomalies: overvoltage, overtemperature, and internal regulator failure. This separation enables priority-based interrupt handling in safety-critical microcontrollers.
