The AD8280 manufactured by the Analog Devices is a hardware-only safety monitor for Lithium Ion battery stacks. The AD8280 has inputs to monitor up to six battery cells and two temperature sensors (either NTC or PTC thermistors).
Power Integrations has introduced the TOPSwitch-JX Family ( TOP264-271 ) that incorporates a 725 V power MOSFET, high voltage switched current source, multi-mode PWM control, oscillator, thermal shutdown circuit, fault protection and other control circuitry onto a monolithic IC .
The LTC4425 IC is a constant-current/constant-voltage linear charger designed to charge a 2-cell supercap stack from a Li-Ion/Polymer battery, USB port or a 2.7V to 5.5V current-limited supply.
The LTC4425 operates as an ideal diode with an low resistance ( 50mΩ on ) making it suitable for high peak-power/low average power applications.
