Product details
Overview
TLE7183FXUMA8 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, 150 ns typical rise/fall times, fixed short-circuit detection with five selectable thresholds, and AEC-Q100 qualification for under-hood applications.
For engineers reviewing the TLE7183FXUMA8 datasheet, TLE7183FXUMA8 pinout, TLE7183FXUMA8 application, or TLE7183FXUMA8 equivalent, key selection criteria include gate drive strength for 400 nC MOSFETs, phase voltage feedback logic encoding (U_fb/V_fb/W_fb), shunt-based current sensing (ISP/ISN/VO), dead time programming (DT), and dual enable (ENA1/ENA2) with inhibit (INH) control.
Technical Context
The TLE7183FXUMA8 integrates three floating high-side drivers with level shifters and three low-side drivers in a single PG-VQFN-48 package, each HS stage powered by dedicated charge pumps (CH1/CL1/CB1 and CH2/CL2/CB2) to sustain full gate drive at VS ≥ 5.5 V. It implements hardware-based shoot-through protection via fixed dead time and monitors overcurrent using configurable VTHOC threshold and shunt amplifier output VO.
Phase voltage feedback is digitized into positive-logic U_fb/V_fb/W_fb signals for microcontroller interpretation, while ERR1/ERR2 report aggregated fault conditions including undervoltage, overvoltage, overtemperature, and short circuit. The device operates with TTL-compatible inputs (IHx active-low, ILx active-high) and supports sleep mode via ENA1/ENA2 deactivation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 5.5 V to 45 V - enables full functionality across cold-crank (5.5 V) to load-dump (45 V) automotive transients |
| Gate Drive Rise/Fall Time | 150 ns typ. - supports PWM switching up to 30 kHz with minimal switching loss in high-current motor phases |
| Short-Circuit Detection | 5 fixed thresholds via VTHOC pin - allows system-level tuning of fault sensitivity without firmware changes |
| Shunt Amplifier Gain | Programmable via external resistors on ISP/ISN - delivers precise current measurement for closed-loop motor control |
| Phase Feedback Encoding | Digital U_fb/V_fb/W_fb outputs - provides noise-immune, logic-level representation of phase voltages for MCU GPIO capture |
| Thermal Rating | Junction temperature −40 °C to +150 °C - qualified for engine bay placement in cooling fan and EPS systems |
| AEC-Q100 Grade | Grade 1 (−40 °C to +125 °C ambient) - meets automotive reliability and stress test requirements |
Pinout & Package
Package: PG-VQFN-48 (7 mm × 7 mm, 0.5 mm pitch, exposed thermal pad).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GH1–GH3, GL1–GL3 | High-side and low-side gate drive outputs | Direct connection to MOSFET gates; GHx drives HS FETs with level-shifted floating supply; GLx drives LS FETs referenced to GND |
| IH1–IH3, IL1–IL3 | Control inputs | IHx active-low, ILx active-high - enables independent PWM control per half-bridge leg with standard logic interface |

| VO, ISP, ISN | Shunt signal conditioning interface | VO = amplified differential output of internal op-amp; ISP/ISN connect to shunt resistor terminals - enables accurate, low-noise current sensing |
| DT, INH, ENA1, ENA2 | Timing and control configuration | DT sets minimum dead time; INH disables all outputs; ENA1/ENA2 enable driver sections - supports functional safety partitioning |
| ERR1, ERR2 | Fault reporting outputs | Open-drain status flags indicating aggregated faults (short circuit, UV/OV, OT) - simplifies MCU interrupt handling |
Key Features
| Feature | Design Value |
|---|---|
| Integrated charge pumps | Two independent charge pump circuits (CH1/CL1/CB1 and CH2/CL2/CB2) sustain high-side gate drive at VS ≥ 5.5 V - ensures reliable startup during battery brownout |
| Hardware shoot-through protection | Fixed dead time insertion between complementary HS/LS switching - prevents destructive cross-conduction without software timing overhead |
| Configurable short-circuit detection | VTHOC pin accepts external voltage to select one of five factory-set thresholds - enables matching to specific MOSFET Rds(on) and layout parasitics |
| Dual enable architecture | Separate ENA1 and ENA2 pins allow independent activation of driver sections - supports ASIL decomposition and diagnostic partitioning |
| Digitized phase feedback | U_fb/V_fb/W_fb outputs encode phase voltage states as logic levels - reduces MCU resource usage versus analog sampling and threshold comparison |

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 |
|---|---|---|---|
| DRV3205-Q1 | Single-supply design (no integrated charge pumps); requires external bootstrap or isolated supply for HS drive | Lacks native low-voltage operation below 6.5 V; no VTHOC-configurable short-circuit threshold | Select when system already provides robust HS supply and simpler fault thresholding suffices |
| MC33883 | Legacy 3-phase driver with slower 300 ns rise/fall; no digitized phase feedback outputs (U_fb/V_fb/W_fb) | Requires external comparators for phase sensing; limited to ≤20 kHz PWM due to timing limitations | Select for cost-sensitive legacy designs where 30 kHz PWM and digital phase feedback are not required |
Compared with DRV3205-Q1 and MC33883, the TLE7183FXUMA8 uniquely combines integrated charge pumps for cold-crank operation, programmable short-circuit detection, and logic-level phase feedback - reducing BOM count and enabling higher-performance motor control in modern automotive ECU platforms.

FAQ
What is the purpose of the VTHOC pin on the TLE7183FXUMA8?
The VTHOC pin sets the overcurrent detection threshold by accepting an external reference voltage; five factory-defined trip points (e.g., 50 mV, 100 mV, 200 mV, etc.) are selected based on this voltage, enabling hardware-tuned short-circuit sensitivity without firmware updates or calibration.
How does the TLE7183FXUMA8 handle low-battery conditions during cold cranking?
It maintains full gate drive capability down to 5.5 V supply via two integrated charge pumps that generate boosted voltages for high-side drivers; this eliminates reliance on external bootstrap diodes or isolated supplies and ensures uninterrupted motor control during automotive cold-crank events.
Can the TLE7183FXUMA8 drive MOSFETs with gate charges exceeding 400 nC?
No - the datasheet specifies 150 ns rise/fall times are guaranteed only for MOSFETs with ≤400 nC total gate charge; driving higher-Q devices may degrade switching performance and increase losses, requiring external gate drivers or careful thermal derating.
What is the function of the U_fb, V_fb, and W_fb pins?
These pins output positive-logic CMOS signals representing the high/low state of motor phases U, V, and W respectively; they provide direct digital feedback to the MCU without analog-to-digital conversion, enabling fast commutation decisions and eliminating external comparators or RC filtering components.
