PRODUCTION DATA.
Special considerations must be taken when using the internal RPD by shorting the QOD pin to the VOUT pin. The internal RPD is a pulldown resistance designed to quickly discharge a load after the switch has been disabled. Care must be used to ensure that excessive current does not flow through RPD during discharge so that the maximum TJ of 125°C is not exceeded. When using only the internal RPD to discharge a load, the total capacitive load must not exceed 200 uF. Otherwise, an external resistor, REXT, must be used to ensure the amount of current flowing through RPD is properly limited and the maximum TJ is not exceeded. To ensure the device is not damaged, the remaining charge from CL needs to decay naturally through the internal QOD resistance and must not be driven.
