Figure 2. Under Voltage Lockout
During Under-Voltage Lock-Out, the output driver is biased to a high impedance state. Pin 6 should be shunted to ground
with a bleeder resistor to prevent activating the power switch with output leakage current.

1.0V
IS(MAX)= ------------
RS
A small RC filter may be required to suppress switch transients.
