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.

Absolute Maximum Ratings

Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be operable above the recommended operating conditions and stressing the parts to these levels is not recommended. In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability. The absolute maximum ratings are stress ratings only.

Output Power Derating

The maximum package power dissipation is 295mW. The package is limited to this level to ensure that under normal operating conditions and over extended temperature range that the semiconductor junction temperatures do not exceed 125°C. The package power is composed of three elements the LED, static operating power of the output IC, and the power dissipated in the output power MOSFET transistors. The power rating of the output IC is 250mW. This power is divided between the static power of the integrated circuit, which is the product of IDD times the power supply voltage VDD VEE . The maximum IC static output power is 150mW, VDD VEE = 25V, IDD = 6mA. This maximum condition is valid over the operational temperature range of -40°C to +100°C. Under these maximum operating conditions, the output of the power MOSFET is allowed to dissipate 100mW of power.

The absolute maximum output power dissipation versus ambient temperature is shown in Figure The output driver is capable of supplying 100mW of output power over the temperature range from -40°C to 87°C. The output derates to 90mW at the absolute maximum operating temperature of 100°C.

Fig. 12 Absolute Maximum Power Dissipation
vs. Ambient Temperature

VDD VEE = Max. = 25V IDD = 6mA LED Power = 45mW

The output power is the product of the average output current squared times the output transistor’s RDS ON :

PO AVG = IO AVG 2
• RDS ON

The IO AVG is the product of the duty factor times the peak current flowing in the output. The duty factor is the ratio of the ‘on’ time of the output load current divided by the period of the operating frequency. An RDS ON of results in an average output load current of 200mA. The load duty factor is a ratio of the average output time of the power MOSFET load circuit and period of the driving frequency.

The maximum permissible, operating frequency is determined by the load supplied to the output at its resulting output pulse width. Figure 13 shows an example of a 0.03µF gate to source capacitance with a series resistance of This reactive load results in a composite average pulse width of 1.5µs. Under this load condition it is not necessary to derate the absolute maximum output current out to 250kHz.
