illustrate

The FOD3180 is a 2A output current, high speed MOSFET gate drive optocoupler. It consists of gallium aluminum arsenide (AlGaAs) light-emitting diodes and integrated circuit power supplies with PMOS and NMOS output power transistors. It is ideal for power mosfets (PDPs) for plasma display panels, motor control inverter applications and high performance DC/DC converters. The device is packaged in an 8-pin dual-in-line housing and is solder compliant with a lead-free 260°C reflow process.

Absolute Maximum Ratings (TA = 25°C unless otherwise noted)

Stresses in excess of the Absolute Maximum Ratings may damage the device. Equipment may not work or be recommended for operation under recommended operating conditions and increase component stress to these levels. Additionally, prolonged exposure to stresses higher than recommended operating conditions may affect device reliability. Absolute Maximum Ratings are stress ratings only.

Recommended Operating Conditions

The Recommended Operating Conditions table defines the conditions for actual equipment operation. Recommendations specify operating conditions to ensure optimum performance to data sheet specifications. Fairchild does not recommend exceeding or designing to absolute maximum ratings.

Output power derating

The maximum package power consumption is 95MW. This package is limited to this level to ensure that the range of normal operating conditions and OTJ junction temperatures does not exceed 125°C. The packaged power consists of three components; the LED, the quiescent operating power output IC, and the power MOSFET transistors dissipated in the output power. The output IC is rated at 250 MW. This force is divided into integrated circuits and it is IDD times the supply voltage (VDD – VEE). The maximum integrated circuit static output power is 150mW, (VDD–VEE)=25V, IDD=6mA. This maximum condition is valid over an operating temperature range of -40°C to +100°C. At maximum operating conditions, the output power MOSFET can dissipate 100mW of power. The absolute maximum output power dissipation at ambient temperature is shown in the graph. The output driver is capable of delivering 100mW of output power over a temperature range from -40°C to 87°C, dropping to 90MW at absolute maximum operation. Temperature 100°C.

The output power is the product of the average output power Current squared times the RDS(on) of the output transistor: PO(average) = IO(average) 2 RDS(on) IO(average) is the duty cycle times the output the peak current. The duty cycle is the output load current "on" time divided by the period at the operating frequency. An RDS(ON) of 2.0Ω results in an average output load current of 200mA. The load duty cycle is the ratio of the average output time of the power MOSFET to the cycle of the load circuit and the drive frequency. The maximum allowable operating frequency is determined by the load on its output. Output pulse width. The figure shows a 0.03µF gate-source capacitance with a series resistance of 8.50Ω. This reactive load results in an average pulse width of 1.5 microseconds. It is not necessary to subtract the absolute maximum output under this load condition. current before the operating frequency exceeds 63kHz.

The graph shows the relationship between the LED input drive current and the device's output voltage, source current and sink current.
