Fast Charging and Safety
Fast charging requires constant monitoring of
battery parameter and precise charging
termination control. The Z8 Encore! XP Flash
MCU allows easy switch over from a constant
current charge to a constant voltage
mechanism for the precise termination of the
charging process needed for battery
applications. Our MCU also has two
independent PWM outputs that provide
simultaneous charging of multiple batteries,
doubling your system's charging capacity.
The high accuracy ADC on the Z8 Encore! XP
prevents overcharging as well. For multiple
safety devices to be built into your system, the
Z8 Encore! XP multi-channel ADC continuously
monitors the output voltage and current of the
DC-DC converter, battery charging current, and
temperature. The 16-bit timer PWMs will then
adjust the output parameters of the DC-DC
converter during normal operation and if a
fault condition happens.
High System Cost
By integrating advanced features into our
MCU, such as the transimpedance amplifier
and the temperature sensor, the Z8 Encore! XP
doesn't need external components like many of
its competitors. Our feature-rich solution gives
you the ability to reduce your overall system
cost while saving precious board space on
your application.
