... U2102B Voltage Monitoring While the operating voltage is being built up or reduced, uncontrolled conditions or output pulses of insufficient amplitude are being suppressed by the internal moni- toring circuit. All latches in the circuit, the divider and the control logic are reset. When the supply voltage is applied, the enable threshold (clamp voltage) of approxi- mately 16 V must be reached so that the circuit is enabled ...
