HV20822FG-G-M931

Analog Switches - Special Purpose Overview

The HV20822FG-G-M931 is a high-voltage analog switch IC manufactured by Microchip Technology, housed in a 48-lead LQFP package. It integrates 16 single-pole single-throw (SPST) channels organized into two independent sets of eight switches. The device operates with a positive supply voltage ranging from +50V to +110V and a negative supply voltage between -10V and VPP minus 220V. Logic control signals are compatible with 5.0V and 12.0V CMOS levels. Key electrical parameters include a maximum on-resistance of 22 Ohms, a turn-on time of 5 microseconds, and a turn-off time of 5 microseconds. The quiescent current consumption is typically 10 microamperes.

Analog Switches - Special Purpose Procurement Notes

Verify the M931 suffix indicates reel packaging containing 1000 units per reel. Confirm RoHS compliance and lead-free status as specified by the -G designation. Ensure procurement documentation matches the specific Supertex/Microchip datasheet version DSFP-HV20822 C071613 for accurate technical validation.

Analog Switches - Special Purpose Selection Notes

Select this component when designing circuits requiring 16-channel high-voltage switching controlled by standard logic levels. Verify that the required analog signal range fits within the VNN to VPP limits. Check thermal resistance requirements for the 48-lead LQFP package if operating near the upper temperature limit of 70°C.

Analog Switches - Special Purpose Part Context

This part belongs to the HV20822 series of high-voltage analog switches originally developed by Supertex Inc., now part of Microchip Technology. The FG variant specifies the 48-lead LQFP package option. The M931 suffix specifically denotes the tape and reel packing format used for automated assembly processes.

Analog Switches - Special Purpose Replacement Considerations

The HV20820FG-G is a related part number in the same family but contains only 8 channels instead of 16. Verify channel count requirements before substitution. No other direct cross-model replacements are documented in the provided source material.

Analog Switches - Special Purpose FAQ

How are the 16 channels controlled?

The 16 channels are divided into two sets of 8. Switches 0 to 7 are controlled by input DIN1, while switches 8 to 15 are controlled by input DIN2. A latch enable (LE) signal determines whether new states are loaded or held.

What is the minimum off-isolation performance?

The device provides a minimum off-isolation of -45 dB at a frequency of 7.5 MHz with a 50-ohm load.

Can the device operate with arbitrary power-up sequences?

Yes, the power-up and power-down sequence for VDD, VPP, and VNN is arbitrary, provided that Ground (GND) is powered up first and powered down last.
