Product details
Overview
TLE9140EQWXUMA1 from Infineon is a 48 V/24 V B6-bridge gate driver IC for BLDC motor control, supporting up to three half-bridges with integrated charge pump for 100% duty cycle operation, 16-bit SPI interface, and AEC-Q100 qualification for automotive use in engine cooling fans, water pumps, and oil pumps.
For engineers reviewing the TLE9140EQWXUMA1 datasheet, TLE9140EQWXUMA1 pinout, TLE9140EQWXUMA1 application, or TLE9140EQWXUMA1 equivalent, key selection criteria include supply voltage range (8–75 V), VDS monitoring capability, cross-current protection, adaptive MOSFET control timing, and diagnostic register access via SPI.
Technical Context
This device implements a multi-channel high-side/low-side gate driver architecture with independent control logic per half-bridge, enabling precise timing coordination between IHx/ILx inputs and GLMx/SHMx outputs. It integrates dual charge pumps (CP1/CP2) to sustain high-side gate drive under extended duty cycles and supports safe switch-off paths during fault conditions.
The SPI interface operates at up to 10 MHz with full-duplex 16-bit frame structure, delivering real-time status registers (e.g., global error flag, temperature warning, VDS overvoltage detection) and configurable control registers for diagnostics, watchdog timeout, and blanking time adjustment.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 8.0 V to 75 V - supports 24 V/48 V platforms with load dump tolerance up to 72 V. |
| Max. Total Gate Charge Drive | 231 nC × 6 @ 25 kHz - enables driving high-Ciss MOSFETs across all six channels simultaneously. |
| Undervoltage Threshold | 20.0 V / 8.0 V - dual-level shutdown prevents erratic operation during brown-out in 48 V/24 V systems. |
| Overvoltage Threshold | 72.0 V / 48.0 V - protects against transients during load dump events in automotive environments. |
| Thermal Shutdown Temp | 150 °C - triggers safe switch-off path to prevent thermal runaway in sealed motor modules. |
| SPI Clock Frequency | Up to 10 MHz - allows fast register read/write for real-time diagnostics and closed-loop timing adjustments. |
| Quiescent Current | 26 µA - ensures ultra-low power consumption in sleep mode for battery-sensitive applications. |
Pinout & Package
Package: PG-TSDSO-32 (thermally enhanced 32-pin exposed-pad SOIC variant with wettable flanks).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 GND | Power Ground Reference | Primary return path for digital and analog supplies; connects to PCB thermal pad for heat dissipation. |
| 2 VDD | Digital Supply Input | Powers internal logic and SPI interface; requires local 3.3 V decoupling when interfaced with MCU. |

| 13 SLM | Low-Side Source Common | Reference node for all low-side MOSFET sources; must be routed with low-inductance trace. |
| 14–16 GLM1–GLM3 | Low-Side Gate Drive Outputs | High-current (±1 A peak) drivers directly connecting to MOSFET gates without external buffers. |
| 17–19 SHM1–SHM3 | High-Side Gate Drive Outputs | Charge-pump-powered outputs capable of sustaining 100% duty cycle on high-side switches. |
| 20–21 CP1P/CP1N | Charge Pump Phase 1 Terminals | Connect external flying capacitor (typically 100 nF) to generate boosted gate voltage for SHMx. |
| 22–23 CP2P/CP2N | Charge Pump Phase 2 Terminals | Second independent charge pump stage for redundancy or higher current capability. |
| 24 VSM | Main Supply Monitor Input | Analog input sensing battery rail; used for UV/OV detection and internal supply regulation. |
| 25 EN | Enable Input | Hardware reset and wake-up pin; asserts safe switch-off path when pulled low. |
| 26–28 DH, IH1, IH2 | Diagnostic/High-Side Monitoring | DH monitors drain-source voltage of high-side MOSFETs for overvoltage and cross-current detection. |
| 29–32 CP1, CP2, GND, N.C. | Charge Pump Outputs & Ground | CP1/CP2 deliver regulated gate drive voltages; GND ties to thermal pad; N.C. is no-connect. |
Key Features
| Feature | Design Value |
|---|---|
| Adaptive MOSFET Control | Adjusts turn-on/off delays dynamically based on temperature and supply voltage to maintain timing accuracy across operating conditions. |
| Off-State Diagnostic | Detects open-load and short-to-battery/ground faults on GLMx/SHMx outputs while gate drivers are inactive. |
| Drain-Source Monitoring (VDS) | Real-time monitoring of high-side MOSFET VDS via DH pin enables instantaneous overvoltage and cross-current detection. |
| Timeout Watchdog | Resets gate outputs if SPI communication stalls beyond programmable timeout window, preventing uncontrolled motor operation. |
| Cross-Current Protection | Hardware-enforced dead-time insertion prevents shoot-through during switching transitions, independent of MCU timing precision. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar BLDC bridge driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DRV3245QRTVRQ1 | Lacks integrated charge pump; requires external bootstrap circuitry for high-side drive; lower max. VS (65 V). | Not qualified for 72 V load dump; limited to 48 V nominal systems without derating. | Choose when cost sensitivity outweighs design simplicity and 72 V transient immunity. |
| STGD18N40LZ | Discrete high-side/low-side driver pair; no SPI interface or diagnostics; no VDS monitoring. | Requires external microcontroller for sequencing, fault handling, and timing calibration. | Choose only for legacy designs where register-level diagnostics and adaptive control are unnecessary. |

FAQ
What is the maximum continuous supply voltage the TLE9140EQWXUMA1 can withstand?
The TLE9140EQWXUMA1 supports a specified supply voltage range of 8.0 V to 75 V, with overvoltage shutdown triggered at 72.0 V for 48 V systems and 48.0 V for 24 V systems. Its absolute maximum rating allows brief exposure to 100 V transients, making it suitable for automotive load dump conditions per ISO 7637-2 Pulse 5a.
Does the TLE9140EQWXUMA1 require external bootstrap capacitors?
No. The device integrates two independent charge pumps (CP1 and CP2) with dedicated pins (CP1P/CP1N, CP2P/CP2N) for external flying capacitors (typically 100 nF), eliminating the need for bootstrap diodes or capacitors and enabling true 100% duty cycle operation on all high-side outputs.
How does the TLE9140EQWXUMA1 handle cross-current protection?
Cross-current protection is implemented via hardware-level blanking time insertion between high-side and low-side switching transitions, enforced independently per half-bridge. It uses internal timing logic synchronized with IHx/ILx inputs and is augmented by real-time VDS monitoring on the DH pin to detect shoot-through before MOSFET damage occurs.
Can the TLE9140EQWXUMA1 operate without an MCU?
No. The device lacks autonomous motor control logic and requires continuous SPI commands from an external microcontroller or MOTIX™ MCU to configure registers, initiate gate drive sequences, and respond to diagnostic flags. It functions strictly as a smart gate driver-not a standalone motor controller.
