What is ICL7660?
ICL7660 is a charge pump voltage converter IC used to invert the input voltage. This IC can be found in instrumentation and memory circuits. If you looking for low current dual supply voltage design then this IC is the correct choice.
What is a MAX1044?
The MAX1044 and ICL7660 are monolithic, CMOS switched-capacitor voltage converters that invert, double, divide, or multiply a positive input voltage. They are pin compatible with the industry-standard ICL7660 and LTC1044. Operation is guaranteed from 1.5V to 10V with no external diode over the full temperature range.
What is a charge pump in electronics?
A charge pump is a kind of DC-to-DC converter that uses capacitors for energetic charge storage to raise or lower voltage. Charge-pump circuits are capable of high efficiencies, sometimes as high as 90–95%, while being electrically simple circuits.
What is the function of charge pump?
Charge-pump voltage converters accomplish energy transfer and voltage conversion using charges stored on capacitors, thus the name, charge-pump. Using switching techniques, charge pumps convert supply voltage of one polarity to a higher or lower voltage, or to an alternate polarity (at either higher or lower voltage).
Where are charge pumps used?
The well-known one is the charge pump circuits. They are widely used in low-power DC–DC converter, especially in power management of the integrated circuits. Usually, they use high-frequency switching actions and only use capacitors to transfer the energy.
What is a charge pump in hydraulic?
A hydraulic charge pump is a fixed displacement pump (typically a gear pump) that feeds the hydrostatic pump loop. Provides flow/pressure source for auxiliary functions such as hydraulic parking brakes and servo circuits. In addition, it can be used to supply pilot pressures.
Why bootstrap is used in MOSFET?
Normally, because the drain voltage is Vin (input voltage), representing the highest voltage in the circuit, any higher voltage must be supplied externally. To generate that high voltage, a bootstrap circuit is used. Use of the high-side transistor as an Nch MOSFET requires a VGS higher than the drain voltage.
What is the purpose of a charge pump?
What is an HST motor?
HST stands for Hydrostatic Transmission and is used in a travel system to connect the hydraulic pump with the motor in a closed circuit enabling continuous speed change from Forward to Stop/Neutral and Reverse or vice versa.
