125 V high-side gate driver protects battery equipment

Infineon Technologies has introduced a 125V high-side gate driver designed to protect battery-powered applications such as cordless power tools, robotics, e-bikes, and vacuum cleaners in the event of a fault.

The Infineon 125V EiceDRIVER 1EDL8011 gate driver provides fast turn-on and turn-off of high-side N-channel MOSFETs with its high gate current capabilities.

It consists of an integrated charge pump with an external capacitor to provide strong start-up. The internal charge pump provides the MOSFET gate voltage when the operating input voltage is low. The gate driver IC manages inrush current and provides fault protection. Undervoltage Lockout (UVLO) protection at input voltage prevents the device from operating under hazardous conditions.

The driver is available in a DSO-8 package, making it ideal for space-constrained designs. It includes overcurrent protection (OCP), adjustable current setting threshold, time delay and a safe start-up mechanism with flexible blanking during MOSFET turn-on transitions.

The 1EDL8011 has a wide operating voltage range of 8 V to 125 V and a high gate sinking current of up to 1 A, allowing for efficient switching. Additionally, the gate driver has an extremely low off-mode quiescent current of 1 µA, helping to minimize power consumption in sleep mode. The device also includes a V DS sense feature that is used to trigger an overcurrent shutdown by monitoring the drain-to-source voltage of the disconnect MOSFET.

The 1EDL8011 is available now.
