The PS200 is a configurable Switch mode chargerwhich is comprised of a PIC16F microcontroller coreand precision analog circuitry. This secTIon explores thehardware features in relaTIon to generic Switch modecharging. Subsequent secTIons will describe the operaTIonof the PS200 with firmware for Lithium-based(Section 2.0 “Lithium Chemistry Algorithm”),Nickel-based (Section 3.0 “Nickel Chemistry Algorithm”)and Lead Acid (Section 4.0 “Lead AcidChemistry Algorithm”) charging.• Oscillator• Power-saving Sleep mode• Power-on Reset (POR)• Brown-out Reset (BOR)• High-Endurance Flash/EEPROM Cell:- 100,000 write Flash endurance- 1,000,000 write EEPROM endurance- Flash/Data EEPROM retention: > 40 years• High-Speed Comparator module with:- Two independent analog comparators• Operational Amplifier module with twoindependent op amps• Two-Phase Asynchronous Feedback PWM• Voltage Regulator• 10-bit (9-bit plus sign) A/D Converter• In-Circuit Serial Programming™ (ICSP™) viatwo pins
