Fonctionnalités et applications
Vishay has released a new isolated IGBT/MOSFET driver which produces a high peak drive current of 2.5A with a high-efficiency, low power-drop MOSFET output stage, sufficient to directly drive high-power IGBTs with a rating up to 1,200V and 100A.
The VOD3120 is an isolated gate driver IC. On receiving a trigger signal from a microcontroller or other control device, it supplies the correct power input to the gate of a high-voltage MOSFET to switch it on fast and efficiently. The trigger signal is coupled optically, not electrically, to the gate drive input, so the high-voltage power transistor circuit is isolated from the low-voltage control circuit.
The VOD3120A is intended for use in high-voltage applications such as induction hobs and solar inverters, in which it can provide isolation for sensitive circuitry that might be damaged by high voltages in fault conditions.
- Solar inverters
- Motor drives
- Uninterruptible power supplies
- Induction hobs
- Compatible with industrial three-phase line voltages
- Highly efficient output drive dissipation
- Can be triggered by embedded digital controllers
- 0.5μs maximum propagation delay time
- Low-power CMOS output stage
- 5mA threshold current
The optical interface is integrated into the VOD3120A IC, which means that designers can achieve isolation in power transistor circuits without the use of an external optocoupler.
