Simple & Inexpensive Ideal-Diode MOSFET Circuit

Good for low-drop diode applications, such as blocking battery back-charging or brownout protection

555 One-Shot Timer Has Zero Quiescent Power: One-shot timer uses no power when quiescent, useful for battery powered circuits
Lead-Acid Battery Charger, 12V 6A, Using Hysteretic SMPS Circuit With Auto Trickle-Charge: Simple, efficient, lead-acid battery charger auto switches from CC to CV (trickle-charge) mode
Power Saving DC Solenoid Driver Provides Initial Full Power Actuation Followed By PWM Hold: Circuit applies full actuation power to solenoid with PWM hold reducing power to 12-25% of nominal
Low-Dropout CC/CV 12V Lead-Acid Battery Charger With Auto Trickle-Charge: Minimal circuit for auto CC/CV charging. Option allows pot adjustment of charge current.
Low Drop, High-Side Sense Current Limiter Adjusts to Zero: Two simple high-side sense current limit circuits adjust to zero current and have low voltage drop
