Energizing Your Innovation
Many new energy harvesting based products can be
enabled by the EnerChip EP:
• Various ambient energy sources can
be harvested to power new designs
using : Photo Voltaic Cells, Piezoelectric
vibration harvesters, Thermoelectric cells,
Electromagnetic harvesters, RF Induction
charging.
• Designs can use ultra low power by leveraging
the Maximum Peak Power Tracking EnerChip
EP capabilities
• The power management communications
interface to the system MCU can be used to
create “Energy Aware” systems
• Input power measurement and status
reporting
• Advanced energy storage management
• Uses digital power controls
Everything is Inside the EnerChip EP
The EnerChip EP uses an advanced Maximum Peak
Power Tracking (MPPT) algorithm that constantly
matches the EH transducer output impedance. MPPT is
the most efficient method of converting energy from an
EH transducer and is superior to charge accumulation
techniques that do not match the impedance of
the transducer to the power conversion stage. The
EnerChip EP operates in multiple modes and can
communicate with microcontrollers. The EP manages
all aspects of energy storage devices/peripherals and
uses intelligent power management during the start-
up initialization sequence. The EP operates at 1/10
the power of other EH power management units.
Ideal for High Efficiency Wireless Sensors
The key to designing energy harvesting-based wireless
sensors with high efficiency power conversion is
to utilize the EnerChip EP along with EnerChip
rechargeable energy storage devices. The EnerChip EP
performs the high efficiency energy conversion, energy
storage and power management. It is the key enabler
of “Zero Power” systems as shown in the following
