Abstract
An electrostatic discharge (ESD) circuit for use with motorized window shades includes an antenna connected to a motor controller having a printed circuit board, a receiver or transceiver, a microprocessor and memory that are connected to and operate a motor. The ESD circuit is connected to the line-in between the antenna and the downstream components of the printed circuit board. The ESD circuit includes an inductor in parallel with two anti-parallel diodes in reverse polarity to one another. The ESD circuit shunts damaging signals or ESD events to ground by providing a lower impedance or lower resistance path to ground for these signals, whereas the ESD circuit allows the signals of interest to pass by the ESD circuit as the ESD circuit provides a higher impedance or higher resistance path to ground as compared to the signal of interest passing through the receiver or transceiver of the motor controller.
