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

capabilities of the EnerChip EP

• 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 “Internet of Things” 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
