Title:
LATCH RELAY CONTROL DEVICE
Document Type and Number:
Japanese Patent JP2022152618
Kind Code:
A
Abstract:
To control a plurality of latch relays individually with a small number of control lines.SOLUTION: A latch relay control device has: N (N is a natural number) latch relays; two pulse generators; and a 2N-stage nonlinear LC ladder circuit connected between the two pulse generators. In each of the N latch relays, a first switch is connected with an S terminal, and a second switch is connected with an R terminal. An upstream side of each varicap diode in odd-numbered stages of the nonlinear LC ladder circuit is connected with a control terminal of each first switch, and an upstream side of each varicap diode in even-numbered stages of the nonlinear LC ladder circuit is connected with a control terminal of each second switch.SELECTED DRAWING: Figure 6
