Infineon offers MOTIX 3-phase gate driver IC with power management

The MOTIX family for automotive and industrial motor-control applications from Infineon Technologies offers a broad product portfolio with various levels of integration. To further expand its offering, Infineon introduces the MOTIX 3-phase gate driver IC 6ED2742S01Q.

The 160 V silicon-on-insulator (SOI) gate driver features an integrated power management unit (PMU) and is available in a QFN-32 package with a thermally efficient exposed power pad.

This makes the easy-to-integrate device ideal for battery-powered industrial BLDC motor-control drives including cordless power tools, robotics, drones, and light electric vehicles (LEVs).

The 6ED2742S01Q has integrated bootstrap diodes that power three external high-side bootstrap capacitors. Through a trickle charge pump, they support 100% duty-cycle operation. Protection features include under-voltage lock-out, overcurrent protection with configurable threshold, fault communication, and automatic fault recovery.

The output drivers integrate a high-pulse current buffer stage designed for minimal driver cross-conduction. In addition, a current sense amplifier (CSA) with selectable gain between the low-side supply voltage (V _SS) and the low-side power ground return (COM) is integrated.

The MOTIX gate driver provides a 1 A source and 2 A sink current with independent under-voltage lock-out (UVLO) for high- and low-side gate drives. The device offers a propagation delay of 100 ns and a minimum dead time of 100 ns with built-in delay matching. As a result, the driver enables high-switching frequencies with reduced level shift losses.

The exposed pad of the QFN-32 provides very low thermal resistance, enabling reliable operation.

The MOTIX 6ED2742S01Q is rated for industrial temperature operation ranging from -40° to 125° C and can easily drive OptiMOS and StrongIRFET MOSFETs in single or parallel combinations. It supports battery voltages from 10.8 to 120 V.
