Integrated power management unit, current detection amplifier, and overcurrent protection function
Suitable for battery-powered industrial BLDC motor control drives

Infineon Technologies (hereafter Infineon) offers a comprehensive product portfolio with various configurations for automotive and industrial motor control applications.

Infineon announced today the launch of its 160V MOTIX™ three-phase gate driver IC with integrated power management unit, current sense amplifier and overcurrent protection.

Infineon's newly launched MOTIX 3-phase gate driver IC, the 6ED2742S01Q, is a 160 V silicon-on-insulator (SOI) gate driver with integrated power management unit (PMU) in a QFN-32 package with exposed power pad for thermally efficient dissipation.

The 6ED2742S01Q, with integrated power management unit, is an ideal IC for battery-powered industrial BLDC motor control drives such as cordless power tools, robotics, drones, and light electric vehicles (LEVs).

The 6ED2742S01Q has a built-in bootstrap diode that powers three external bootstrap capacitors.

This diode supports 100 percent duty cycle operation via a trickle charge pump.

Protection features include undervoltage protection, overcurrent protection (threshold can be set), and error protection. Includes fault information transfer and automatic error recovery capabilities.

The output driver uses a buffer stage with high pulse current specifications to minimize driver cross-conduction.

It also has a built-in current sensing amplifier (CSA) between the low-side supply voltage (VSS) and the low-side power ground return (COM), and the gain of this amplifier can be selectively adjusted.

This MOTIX gate driver provides 1A source current and 2A sink current and features independent undervoltage lockout (UVLO) for high-side and low-side gate drives.

This gate driver has a propagation delay time of 100ns and a minimum deadtime of 100ns through delay matching, enabling high switching frequency and reducing level shift losses.

The exposed pad of the QFN-32 package has very low thermal resistance, enabling stable operation.

The MOTIX 6ED2742S01Q operates over the industrial temperature range of -40°C to 125°C, easily drives OptiMOS™ and StrongIRFET™ MOSFETs in single or parallel combinations, and operates from battery voltages of 10.8 V to 120 V.
