microHVA-2 - Dual MFC channel High Voltage Power Amplifier

The microHVA-2 is a triple output power supply with one fixed 500V output, and two variable outputs from 0V to 2 kV. This power supply is specifically designed for driving P1 type MFCs. Use of the bias supply allows a voltage range of -500V to +1500V to be applied simultaneously to two different MFCs or MFC groups. For the output voltage control, the microHVA-2 provides four jumper-selectable interfaces, an analog interface, a PWM interface, an 8-bit I²C interface, and a 12-bit I²C interface. It is designed for battery operation and requires a DC supply voltage from 12V to 16V.

Specifications:

Voltage Output Range	Two variable supplies from 0 to 2000V. One fixed 500V supply, for negative bias.
Current Output Range	0V to +2000V: 0mA to 1.5mA, 3W +500V: 0mA to 10mA, 5W
Input Voltage	+12 to +16V DC. Maximum current 2A (during charging).
External Voltage Control Input	The control input operates over a 0 to 5V range for a 0 to 2000V output (factor 400 amplification). Signal frequency range is 0Hz to 250Hz, depending on the connected capacitance (MFC) and voltage swing on the output channel. Overvoltage and negative voltage protected. An enable input shuts down all outputs to save power consumption and for safety.
PWM Control Input	1ms to 2ms corresponds to -500V to +1500V across the output channels and negative bias. Repetition rate is 50Hz nominally, minimum 5Hz and maximum 300Hz
I²C Control Interface	The I²C slave address is: 0x78 hex. The I2C Bus interface supports four data transfer speeds from 100kb/s to 3.4Mb/s.
Mechanical Dimensions	PCB Dimensions W x D x H = 45mm x 67mm x 18mm. Components are mounted on both sides of the PCB. Note - High voltages are present on both sides of the PCB
