... U2102B Power Supply, Synchronization Pins 15 and 16 The voltage limitation circuit contained in the U2102B enables simple power supply via a dropping resistor R In the case of dc loads, practically all the supply current flows into Pin 16 (the pull down resistor at Pin 16 is neces- sary in order to guarantee reliable synchronization) and ...

... 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 ...
