TIMING DIAGRAM
1.Input/Output Timing Diagram
When input signal is “L”, then output signal “H”.

2.VBS Supply Under Voltage Lockout Timing Diagram
When VBS Supply Voltage keeps lower UV Trip Voltage (VBSuvt = VBSuvr – VBSuvh) for VBS Supply UV Filter Time, output
signal becomes “L”. And then, VBS Supply Voltage is higher UV Reset Voltage, output signal keeps “L” until next input
signal is “L”.

3.Allowable supply voltage transient
Firstly, supply VCC with voltage. Secondly, supply VBS with voltage. In the case of shutting off supply voltage, shut off
VBS Supply Voltage firstly. Secondly, shut off VCC Supply Voltage.
In case VBS or VCC is started too fast, output signal may be “H”.

As shown by the solid line of the timing chart, the output on-resistance drops at ‘VOth’ level when the output is in the ‘L’
state (output level falls). Below the ‘VOth’ level, the output level falls more steeply.
