Universal Relay Driver

The HV9901 universal relay driver provides high-efficiency driving for low-voltage relays with supply voltages as high as 450V. For example, a relay with a 5V coil can be driven directly from the rectified 120 VAC or 230 VAC line.\n\n The IC includes two high-voltage linear regulators. The firs • 10 to 450V input voltage range\n• Energy saving hold current mode\n•Adjustable microcontroller supply\n• Low supply current <1.0mA\n• Constant current coil\n• Programmable pull-in current, pull-in time, and hold current\n• Efficient PWM operation using the relay coils’ inductance;
