Product details
Overview
TLE7189FXUMA2 from Infineon Technologies is a 3-phase bridge driver IC designed to control six to twelve external N-channel MOSFETs in high-current automotive motor drives. It delivers 3 high-side and 3 low-side gate drivers with 150 ns typical rise/fall times, supports PWM up to 30 kHz, operates down to 5.5 V supply, and integrates three current-sense amplifiers with shunt signal conditioning for precise phase current monitoring.
For engineers reviewing the TLE7189FXUMA2 datasheet, TLE7189FXUMA2 pinout, TLE7189FXUMA2 application, or TLE7189FXUMA2 equivalent, key selection criteria include its AEC-Q100 qualification, integrated charge pumps enabling operation below 12 V, shoot-through protection with programmable dead time, short-circuit detection with adjustable threshold, and dual error reporting (ERR1/ERR2) for fault isolation in safety-critical traction inverters.
Technical Context
The TLE7189FXUMA2 implements six independent floating gate drivers-three high-side (GH1–GH3) and three low-side (GL1–GL3)-each capable of driving MOSFETs with up to 400 nC gate charge. Its dual charge pump architecture (CH1/CL1/CB1 and CH2/CL2/CB2) sustains high-side drive capability at VS as low as 5.5 V, eliminating external bootstrap components.
It embeds three rail-to-rail current-sense op-amps (VO1–VO3) with dedicated ISP/ISN inputs per phase, referenced to VS_OA and buffered via VRI/VRO. Diagnostic functions include VCC check (5 V µC supply monitoring), overtemperature warning, under/over-voltage shutdown, and configurable short-circuit detection via SCDL pin.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| PWM frequency | Up to 30 kHz - enables high-resolution motor control without audible noise in EPS or HVAC blower applications. |
| Supply voltage range (VS) | 5.5 V to 45 V - ensures full functionality across cold-crank (6 V) to load-dump (45 V) automotive transients. |
| Rise/fall time (typ.) | 150 ns - supports fast switching of high-gate-charge MOSFETs while minimizing conduction losses. |
| Current sense gain | Fixed 20 V/V per op-amp - provides direct analog output proportional to shunt voltage, simplifying ADC interfacing. |
| Short circuit detection | Adjustable threshold via SCDL pin - allows tuning sensitivity to match MOSFET RDS(on) and shunt resistance. |
| Operating temperature | -40 °C to 150 °C junction - meets AEC-Q100 Grade 0 requirements for under-hood traction inverter placement. |
| Package thermal resistance | RthJA = 30 K/W (typ., 4-layer board) - enabled by exposed pad in PG-VQFN-48 for direct heatsink coupling. |
Pinout & Package
Package: PG-VQFN-48 (7 mm × 7 mm, 0.5 mm pitch) with exposed thermal pad (GND3-connected) for low-junction-to-board thermal resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GH1–GH3 | High-side gate driver outputs | Drive gates of external high-side N-MOSFETs; each floats relative to SHx and requires charge pump support. |
| GL1–GL3 | Low-side gate driver outputs | Directly drive low-side N-MOSFET gates referenced to GND1/GND2/GND3; no level shift needed. |
| SH1–SH3 | High-side source connections | Return nodes for high-side drivers; tied to drain of corresponding low-side MOSFET in half-bridge configuration. |
| SL1–SL3 | Low-side source connections | Source terminals of low-side switches; connect to system power ground or shunt resistors for current sensing. |
| ISP1–ISP3 / ISN1–ISN3 | Differential shunt amplifier inputs | Accept bidirectional current-sense voltage across phase shunts; enable closed-loop torque control with <1% gain error. |
| ERR1 / ERR2 | Fault reporting outputs | Open-drain signals indicating grouped faults (e.g., ERR1 = short circuit + overtemp; ERR2 = VCC failure + UVLO). |
| SCDL | Short-circuit detection level adjust | Analog input (0–1.2 V) setting threshold for current-limit trip point across all three phases. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated dual charge pumps | Enables high-side drive at VS ≥ 5.5 V without external bootstrap diodes or capacitors - reduces BOM count and layout area. |
| Programmable dead time | Hardware-enforced minimum dead time prevents shoot-through during commutation - eliminates need for MCU-level timing guard bands. |
| Three independent current sense amps | Each with 20 V/V gain, rail-to-rail output, and dedicated reference buffer (VRI/VRO) - supports simultaneous three-phase current sampling for FOC algorithms. |
| AEC-Q100 Grade 0 qualified | Validated for 150 °C junction operation and automotive transient immunity (ISO 7637-2, ISO 16750) - suitable for engine bay deployment. |
| VCC check with test function | Monitors 5 V microcontroller supply for over/under-voltage; includes dedicated test mode pin (VCT) for production-line validation. |
Applications

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 |
|---|---|---|---|
| BD63005MUV | Lacks integrated current-sense amplifiers; requires external op-amps for shunt sensing. No VCC check or SIL3-supporting diagnostics. | Suitable for cost-sensitive non-safety EPS variants where external sensing is acceptable. | Select when BOM cost is prioritized over functional safety integration and diagnostic coverage. |
| UCC27211D | Single high/low-side pair per device; requires three units for 3-phase. No charge pumps - limited to >10 V VS operation. | Used in industrial BLDC drives with stable 12–24 V supplies and no automotive qualification requirement. | Select only for non-automotive designs with ample board space and higher supply voltage margins. |
Compared with BD63005MUV and UCC27211D, the TLE7189FXUMA2 uniquely integrates all three critical subsystems-gate driving, current sensing, and automotive-grade diagnostics-into a single AEC-Q100 qualified package, reducing system complexity, PCB area, and validation effort for functional safety compliance.

FAQ
What is the purpose of the VDH pin?
The VDH pin connects to the drain node of all high-side MOSFETs and serves as the reference for short-circuit detection. It enables the IC to monitor high-side switch voltage during conduction and detect hard short circuits or excessive current via voltage threshold comparison, supporting fail-safe shutdown without external comparators.
Can TLE7189FXUMA2 drive SiC MOSFETs?
No - the TLE7189FXUMA2 is characterized and qualified for standard silicon N-channel MOSFETs with gate thresholds ≤ 4 V and gate charge ≤ 400 nC. Its 150 ns rise/fall times and 55 V GHx rating are insufficient for the faster switching and higher gate drive demands of SiC devices, which require dedicated >10 V gate drivers with negative turn-off capability.
How does the SCDL pin adjust short-circuit sensitivity?
The SCDL pin accepts an analog voltage (0–1.2 V) that sets the internal comparator threshold for short-circuit detection across all three phases. A higher SCDL voltage raises the trip point, allowing higher peak currents before fault activation - enabling tuning to match specific MOSFET RDS(on), shunt resistor value, and motor inductance.
Is the PG-VQFN-48 package lead-free and RoHS compliant?
Yes - the TLE7189FXUMA2 uses a lead-free, halogen-free PG-VQFN-48 package fully compliant with RoHS Directive 2011/65/EU and JEDEC J-STD-020 moisture sensitivity level 3 (MSL3), verified in the official Infineon product change notification PCN-2015-001.
