Product details
Overview
6EDL7151XUMA1 from Infineon is a three-phase smart gate driver IC for BLDC and PMSM motor control, integrating three half-bridge drivers (1.5 A sink/source), programmable gate drive voltage (7/10/12/15 V), independent high-/low-side slew rate control, 600 mA synchronous buck converter, 300 mA 3.3 V/5 V LDO, three current sense amplifiers with adjustable gain/offset, and SPI-configurable protections. It targets battery-powered power tools and robotic lawn mowers.
For engineers reviewing the 6EDL7151XUMA1 datasheet, 6EDL7151XUMA1 pinout, 6EDL7151XUMA1 application, or 6EDL7151XUMA1 equivalent, key selection considerations include 70 V max operating voltage, 1PWM/3PWM/6PWM input support up to 200 kHz, VDS-based MOSFET protection, locked rotor detection, and thermally enhanced 48-pin VQFN (7 mm × 7 mm, 0.5 mm pitch) packaging.
Technical Context
The device implements a fully integrated three-phase gate driver architecture with separate charge pumps enabling 100% duty cycle operation and low-voltage supply compatibility. Its SPI interface enables real-time configuration of dead time, slew rate, current sense amplifier gain, and fault thresholds.
It combines analog sensing (three differential current sense amplifiers with blanking, auto-zero, and RDSON/shunt modes), digital supervision (programmable VDS sensors, OTW/OTS, watchdog timers), and power management (buck + LDO + dual charge pumps) in a single chip for closed-loop motor control systems requiring high precision and robustness.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Operating Voltage | 5.5 V to 70 V - supports wide-input battery systems including 18 V–60 V power tools and e-bikes. |
| Gate Drive Current | ±1.5 A peak - sufficient to rapidly switch N-channel MOSFETs in high-power BLDC inverters. |
| Gate Drive Voltage | 7 V / 10 V / 12 V / 15 V programmable - optimizes RDS(on) vs. Miller capacitance trade-off per application. |
| PWM Input Modes | 1PWM, 3PWM, 6PWM up to 200 kHz - enables flexible commutation schemes including trapezoidal and Hall-sensor-based control. |
| Current Sensing | Three amplifiers with 10–100× gain, offset trim, and blanking - supports bidirectional shunt or RDSON sensing with <1 µs settling. |
| Integrated Power | 600 mA buck (adjustable output), 300 mA LDO (3.3 V or 5 V) - powers MCU and analog circuitry with low-noise, high PSRR regulation. |
| Protection Features | VDS monitoring, OCP (buck/LDO/current sense), UVLO/OVLO, OTW/OTS, watchdog timers, locked rotor detection - configurable via SPI with latched fault reporting. |
Pinout & Package
Supplied in thermally enhanced PG-VQFN-48-78 package (7 mm × 7 mm, 0.5 mm pitch) with exposed thermal pad for efficient heat dissipation in motor drive applications.

Key Features
| Feature | Design Value |
|---|---|
| Independent slew rate control | Per high-side and low-side driver - reduces EMI without compromising switching speed or efficiency. |
| RDSON + shunt sensing mode | Single IC supports both sensing topologies - eliminates need for external current sense resistors in cost-sensitive designs. |
| Programmable VDS monitoring | Real-time MOSFET drain-source voltage supervision - enables fast overcurrent and short-circuit protection independent of current sense path. |
| Locked rotor detection | Dedicated watchdog timer with Hall sensor input validation - triggers fault before thermal damage occurs during stalled motor conditions. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar three-phase smart gate driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STSPIN32F0B | Integrated 32-bit ARM Cortex-M0 MCU + gate driver; no VDS sensing; lower max voltage (60 V); 300 mA buck only. | Best for firmware-defined control where real-time current/VDS processing is handled on-chip. | Choose when embedded motor control algorithm execution is required alongside gate driving. |
| MP6550GQ | Three-phase gate driver only (no buck/LDO/current sense amps); 1.2 A drive; 65 V max; requires external power and sensing components. | Suitable for designs with existing power rails and dedicated ADC/microcontroller for sensing and protection. | Choose when full system-level design flexibility and component-level optimization are prioritized over integration. |
Compared with STSPIN32F0B and MP6550GQ, the 6EDL7151XUMA1 uniquely combines high-voltage capability (70 V), integrated power (buck + dual LDO), and analog sensing (three CSA + VDS monitors) in one package-enabling faster time-to-market for robust, self-contained motor modules without sacrificing configurability.

FAQ
What PWM input configurations does the 6EDL7151XUMA1 support?
The 6EDL7151XUMA1 supports 1PWM (with Hall sensor or trapezoidal commutation), 3PWM (three complementary pairs), and 6PWM (six independent gate signals) modes, all operable up to 200 kHz. Each mode includes programmable dead time insertion and optional braking sequences. The SPI interface allows runtime switching between modes without hardware changes.
How does the VDS sensing function protect external MOSFETs?
VDS sensing uses internal comparators to monitor drain-source voltage of each external MOSFET in real time. Thresholds and filter times are SPI-programmable; exceeding the threshold triggers immediate gate shutdown and nFAULT assertion. This provides fast overcurrent and short-circuit protection independent of current sense amplifier latency or shunt resistor tolerance.
Can the current sense amplifiers operate in both shunt and RDSON modes simultaneously?
No-the current sense amplifiers are configured per channel for either shunt resistor sensing (via CSx_P/CSx_N) or RDSON sensing (via direct connection to phase nodes), but not both simultaneously on the same channel. Configuration is done via SPI register settings and applies uniformly across all three channels.
What thermal performance advantages does the 48-pin VQFN package provide?
The PG-VQFN-48-78 package features an exposed thermal pad and optimized copper layout that achieves ≤3.5 °C/W junction-to-case thermal resistance. This enables continuous 1.5 A gate drive operation at ambient temperatures up to 105 °C without forced airflow-critical for sealed power tool and robotic mower enclosures.
