... Timers 1. Description The timer control circuit U2102B is based on bipolar technology. The output stage can switch either a MOSFET or an IGBT. Two sensor inputs and the retriggerable and adjustable tracking time useful for a wide range of applications. By using the reverse phase-control technique, the resistive load can be dimmed without the need of a com- pensation inductance ...

... Power Supply, Synchronization Pins 15 and 16 The U2102B’s voltage limitation circuit enables the power supply via the dropping resistor R the case of DC loads, the entire supply current flows into pin 16 and is supplied via an internal diode to pin 15, where the resultant supply voltage is limited and smoothed by C resistor at pin 16 is necessary in order to guarantee reliable synchronization ...

... Chip Temperature Monitoring The U2102B includes a chip temperature monitoring circuit which disables the output stage when a temperature of approximately 140°C is reached. The circuit will only be enabled again after cooling down and when the operating voltage has been additionally switched off and on. ...

... Current Monitoring The U2102B’s current monitoring circuit represents a double electronic fuse. The circuit mea- sures the current flowing through the power switch by means of the voltage drop across the shunt resistor R due to a high load current (e.g., short circuit), the switch-off latch is set and the switching output pin 11 closes immediately ...
