Product details
Overview
TLE7189FXUMA1 from Infineon Technologies is a 3-phase high- and low-side MOSFET bridge driver IC for automotive motor control, featuring six independent gate drivers (3 high-side + 3 low-side), integrated current-sense amplifiers (x3), short-circuit protection with adjustable detection level, and operation down to 5.5 V supply voltage. It drives external N-channel MOSFETs up to 400 nC gate charge with ~150 ns rise/fall times and supports PWM frequencies up to 30 kHz.
For engineers reviewing the TLE7189FXUMA1 datasheet, TLE7189FXUMA1 pinout, TLE7189FXUMA1 application, or TLE7189FXUMA1 equivalent, key selection criteria include gate drive strength at low battery voltage, integrated shunt signal conditioning, shoot-through protection timing, and AEC-Q100 qualification for under-hood motor control systems.
Technical Context
The TLE7189FXUMA1 implements dual charge pump circuits (CH1/CL1/CB1 and CH2/CL2/CB2) to sustain high-side gate drive above VS during low-input-voltage conditions (≥5.5 V), enabling full 0–100% duty cycle operation. Its level-shifter architecture isolates logic-level inputs from floating high-side domains while maintaining precise dead-time control.
Three dedicated current-sense op-amps (VO1/VO2/VO3 with ISP/ISN inputs) provide galvanically isolated, rail-to-rail output shunt amplification with internal bias reference (VRI/VRO). Diagnostic logic monitors VCC, overtemperature, overvoltage, undervoltage, and short-circuit events via ERR1/ERR2 pins and SCDL-adjustable threshold.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | VS = -4 V to 45 V; enables robust operation across cold-crank (5.5 V min functional) and load-dump transients. |
| Gate Drive Capability | Drives 400 nC MOSFETs with ~150 ns rise/fall; ensures fast switching and reduced conduction losses in high-current inverters. |
| PWM Frequency Support | Up to 30 kHz; suitable for high-resolution field-oriented control (FOC) of BLDC and PMSM motors. |
| Current Sense Channels | 3 integrated op-amps with ±100 mV input range and rail-to-rail output; eliminates external amplifiers for phase current feedback. |
| Protection Functions | Short-circuit detection (adjustable via SCDL), shoot-through prevention, UV/OV shutdown, overtemperature warning, VCC check. |
| Qualification | AEC-Q100 Grade 0 (-40 °C to +150 °C junction); certified for safety-critical automotive powertrain and chassis applications. |
| Package Thermal Performance | PG-VQFN-48 with exposed thermal pad; enables >3 W continuous power dissipation with proper PCB copper layout. |
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 / low-side gate drive outputs | Direct connection to MOSFET gates; each pair (e.g., GH1/SL1) forms one half-bridge leg with integrated dead-time control. |
| SH1–SH3, SL1–SL3 | High-side drain / low-side source connections | Provide floating domain references for level shifters and short-circuit detection (VDH tied to SHx nodes). |
| ISP1–ISP3, ISN1–ISN3, VO1–VO3 | Shunt amplifier inputs/outputs | Enable bidirectional current sensing per phase using low-value shunts; VOx outputs interface directly to MCU ADCs. |
| ENA, INH, IHx, ILx | Control logic inputs | TTL-compatible enable/inhibit and individual high-/low-side switch controls; support independent PWM modulation per leg. |
| ERR1, ERR2 | Diagnostic status outputs | Open-drain fault indicators with priority encoding; ERR1 signals critical faults (short-circuit, OV/UV), ERR2 reports warnings (OT, VCC check fail). |
| VCT, SCDL, VDH | Test and protection configuration | VCT enables VCC check validation; SCDL sets short-circuit threshold voltage; VDH monitors high-side drain voltage for desaturation detection. |
Key Features
| Feature | Design Value |
|---|---|
| Dual integrated charge pumps | Enables reliable high-side drive at VS ≥ 5.5 V without external bootstrap components or diodes. |
| Adjustable short-circuit detection | SCDL pin allows fine-tuning of desaturation threshold from 0.2 V to 1.2 V, matching diverse MOSFET RDS(on) and shunt values. |
| Three independent current sense amps | Eliminates need for external op-amps or isolated amplifiers; supports simultaneous three-phase current sampling with matched gain/offset. |
| SIL3-supporting diagnostics | VCC monitoring, test functions for short-circuit and VCC check, and error prioritization meet ASIL-C requirements for functional safety compliance. |
| Low-EMI gate drive architecture | Controlled slew rates and integrated dead-time prevent shoot-through and reduce radiated emissions in noisy automotive environments. |

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 VDH-based desat detection. | Targeted at cost-sensitive non-safety applications where external sensing is acceptable. | Select when BOM cost outweighs integration benefit and functional safety is not required. |
| UCC27211D | Single high/low-side driver pair only; no multi-phase coordination, no diagnostics, no charge pumps. | Requires three separate ICs plus external logic for 3-phase control; unsuitable for compact automotive modules. | Choose only for discrete, non-integrated designs with ample board space and external protection circuitry. |
Compared with BD63005MUV and UCC27211D, the TLE7189FXUMA1 delivers higher integration (3× current sense, dual charge pumps, diagnostics), automotive qualification, and functional safety readiness-reducing system-level design effort and validation scope for EPS, brake, and HVAC inverters.

FAQ
What is the minimum operating supply voltage for reliable high-side gate drive?
The TLE7189FXUMA1 maintains full high-side gate drive functionality down to VS = 5.5 V thanks to its dual integrated charge pumps. Below this, the high-side outputs may not sustain sufficient gate voltage for full enhancement of standard N-channel MOSFETs, though low-side operation remains functional. This enables uninterrupted operation during automotive cold-crank conditions.
How does the SCDL pin adjust short-circuit detection sensitivity?
The SCDL pin accepts an external voltage (0.2 V to 1.2 V) that sets the threshold for desaturation detection on all three high-side switches. A higher SCDL voltage raises the VDH-to-VS_OA differential required to trigger ERR1, allowing customization for different MOSFET RDS(on), shunt resistor values, or system noise margins without changing hardware.
Can the TLE7189FXUMA1 drive both N-channel and P-channel high-side MOSFETs?
No - the TLE7189FXUMA1 is designed exclusively for N-channel high-side MOSFETs, using charge-pump-based floating gate drive. Its GHx outputs are configured for high-side N-MOS gate control with referenced source (SHx) and drain monitoring (VDH). It does not support P-channel high-side configurations or depletion-mode devices.
Is the PG-VQFN-48 package lead-free and RoHS-compliant?
Yes - the TLE7189FXUMA1 uses a lead-free PG-VQFN-48 package and is fully RoHS-compliant (2011/65/EU) and REACH-conformant. The "XUMA1" suffix denotes tape-and-reel packaging with green (halogen-free) molding compound, meeting automotive environmental standards including JESD204B and AEC-Q200 stress testing for passive components in the same assembly.
