Low power timer circuit
Source: InternetPublisher:睡不醒的小壮 Keywords: Low power consumption timer circuit CMOS switch Updated: 2021/06/28
Shown is a low-power timer circuit , which is mainly
composed of a high-voltage CMOS programmable timer integrated circuit CD4541 and a power supply circuit. When the
start switch is operated , ICI conducts vri, relay Kl operates, KlII contacts self-lock, and KI-2
closes to supply power to the load.
