Ideal Diode
An Ideal Diode is a MOSFET-based active rectifier circuit integrated inside a health management chip/PMIC.It replaces traditional physical diodes, simulates diode unidirectional conduction, but with ultra-low forward voltage drop and low power loss.
Core Features
1.Near-zero forward voltage drop, much lower power dissipation than ordinary Schottky diodes.
2.Reverse current blocking, prevent battery reverse discharge and back-feed current.
3.Fast response, built-in overvoltage/overcurrent protection.
4.Low quiescent current, suitable for battery-powered systems.
Application Scope
1.Battery power path switching, backup power automatic switching.
2.Wearable devices, medical portable equipment, IoT products.
3.Health management chip power input port protection.
4.Solar power supply, multi-power source seamless switching.
ORing Controller
An ORing Controller is a dedicated control module in power/health management chips, used for parallel redundant power supply OR-ing control.
It controls ideal diodes or power MOSFETs to realize multiple power sources parallel input and automatic hot swap.
Core Features
1.Realize multi-rail power OR-ing: auto select the higher voltage power supply to supply the system.
2.Prevent current reverse flow between parallel power supplies.
3.Support hot plug / hot swap, no surge current when plugging/unplugging power.
4.Integrated fault monitoring, match voltage/current/temperature monitor of health management chip.
5.High reliability for redundant power system.
Application Scope
1.Server, industrial equipment redundant power supply parallel system.
2.Medical equipment, communication base station dual-power backup system.
3.Battery + adapter dual-power automatic switching circuit.
4.High-reliability industrial control, automotive electronics power management.
