Infineon’s EiceDRIVER 125V high-side gate driver

To achieve this functionality, it is common to use high-side disconnect switches (e.g. MOSFETs) to prevent a load short circuit from affecting the battery. Infineon Technologies has now introduced the EiceDRIVER 1EDL8011, a 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 device 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 to 125V and a high gate sinking current of up to 1A, allowing for efficient switching. Additionally, the product has an extremely low off-mode quiescent current of 1 µA, helping to minimise 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.

Infineon will be showcasing a demo featuring the 1EDL8011 at its global technology forum OktoberTech 2024 in Silicon Valley on 17 October.
