NiCD - Charging circuit - Using PIC

[ScaleRobotics]

A lot of people like the Allegro hall effect current sensing devices.

Key features:

• Low insertion loss; power dissipation much less than shunt solution
• Able to monitor both AC and DC currents
• Smaller form factor than shunt and current transformer solutions
• 5 V, single supply operation
• Voltage isolation rating certified by TUV America
• RoHS compliant

The devices for 5 up through 30 amp are bi-directional, and are on a 8 pin soic.
