tm

Description
The FOD3181 is a 0.5A Output Current, High Speed MOSFET Gate Drive Optocoupler. It consists of a gallium aluminum arsenide (AlGaAs) light emitting diode optically coupled to a CMOS integrated circuit with a power stage. The power stage consists of a PMOS pullup and a NMOS pull-down power transistor. It is ideally suited for high frequency driving of MOSFETs used in Plasma Display Panels (PDPs), motor control invertor applications, and high performance DC/DC converters. The device is packaged in an 8-pin dual in-line housing compatible with 260 C reflow processes for lead free solder compliance.

85 C 0.5A minimum peak output current High speed response: 500ns max propagation delay over temperature range Wide VCC operating range: 10V to 20V 5000Vrms, 1 minute isolation Minimum creepage distance of 7.0mm Minimum clearance distance of 7.0mm C-UL, UL and VDE approved 10kV/ s minimum common mode rejection (CMR) at VCM 1,500V RDS(ON) of 1.5 (typ.) offers lower power dissipation

Applications
Plasma Display Panel High performance DC/DC convertor High performance switch mode power supply High performance uninterruptible power supply Isolated Power MOSFET gate drive Requires V ordering option
