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 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 2.0Ω 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 8.50Ω. 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 until the frequency of operation exceeds 63kHz. The absolute maximum output power dissipation versus ambient temperature is shown in Figure 12. 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.

The 0.03µF capacitor load represents the gate to source capacitance of a very large power MOSFET transistor. A single supply voltage of 20V is used in the evaluation. This device is tested and specified when driving a complex reactive load. The load consists of a capacitor in the series with a current limiting resistor. The capacitor represents the gate to source capacitance of a power MOSFET transistor. The test load is a 0.03µF capacitor in series with an 8.5Ω resistor. The LED test frequency is 10.0kHz with a 50% duty cycle. The combined IOH and IOL output load current duty factor is 0.6% at the test frequency.
