IL2010B PHASE CONTROL CIRCUIT FOR CURRENT FEEDBACK
Description
The IL2010B is designed as a phase-control circuit in bipolar technology. It enables loadcurrent detection and has a soft-start function as well as reference voltage output. Motor control with load-current feedback and overload protection are preferred applications.
Features
* Full wave current sensing * Mains supply variation compensated * Programmable load-current limitation with over- and high-load output * Variable soft-start * Voltage and current synchronization * Automatic retriggering switchable * Triggering pulse typical 125 mA
* Internal supply voltage monitoring * Current requirement 3 mA * Temperature compensated reference voltage
Applications
* Advanced motor control * Grinder * Drilling machine
