The MOTIX family for automotive and industrial engine control applications from Infineon Technologies offers a broad product portfolio with multiple levels of integration. To further expand its offering, Infineon introduces the MOTIX IC 6ED2742S01Q three-phase gate driver.
The 160V silicon-on-isolator (SOI) gate driver features an integrated power management unit (PMU) and is available in a QFN-32 package with a thermally efficient exposed power block.
This makes the easy-to-integrate device ideal for battery-powered industrial BLDC motor control units, including cordless power tools, robotics, drones and light electric vehicles (LEVs).
The 6ED2742S01Q has integrated bootstrap diodes that power three external bootstrap capacitors on the top side. Through a slow charge pump, they support 100% duty cycle operation. Protection features include undervoltage blocking, overcurrent protection with configurable threshold, fault reporting, and automatic fault recovery.
The output drivers integrate a high pulse current buffer stage designed for minimal driver cross conduction. Additionally, a current sense amplifier (CSA) with selectable gain between low-side supply voltage (V SS ) and low-side power ground return (COM) is integrated.
The MOTIX gate driver provides a 1 A source and 2 A sink current with undervoltage independent lockout (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 allows high switching frequencies with reduced losses due to level change.
The QFN-32's exposed pad offers very low thermal resistance, allowing for 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. Supports battery voltages from 10.8 to 120 V.
