AD8280 safety monitor for Lithium Ion battery

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).

TOPSwitch-JX Family

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 .

LTC4425 linear supercap charger

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.
