Mitsubishi launches dual low-side driver

TOKYO, JAPAN: Mitsubishi Electric Corp. launched a dual low-side driver with over-current detection to drive power modules in inverter systems and air-conditioning systems.

Dual inputs and outputs on the same chip achieve an interleave control system that cancels current ripples by 180-degree phase difference in divided power supplies for high efficiency and low noise.

The one-chip control has been achieved with dual inputs and outputs suitable for interleave control system. Built-in over-current detection circuit reduces external components and simplifies system design. Detection of over-current or under-voltage lockouts can be signaled, thanks to a built-in fault signal output (Failure Output) function and a capacitor with a failure-output pulse width timer function.
