HV20822TQ-G-M931

Analog Switches - Special Purpose Overview

The HV20822TQ-G-M931 is a high-voltage analog switch IC manufactured by Microchip Technology, originally developed by Supertex Inc. It features 16 channels configured as two sets of eight single-pole single-throw (SPST) switches. The device utilizes HVCMOS technology to support operating conditions up to 220V. Key electrical parameters include a maximum on-resistance of 22 Ohms and a logic supply voltage range of 4.75V to 12.6V. High voltage supplies operate between -10V to +110V for VPP and -220V to -10V for VNN. The component operates within a temperature range of 0°C to +70°C and is housed in a 48-lead LQFP package.

• High voltage printing applications

Analog Switches - Special Purpose Procurement Notes

Verify the specific ordering suffix against official documentation to confirm packaging type and compliance status. Ensure that the procurement source provides valid traceability data. Confirm RoHS compliance details directly with the manufacturer or authorized distributor before finalizing orders.

Analog Switches - Special Purpose Selection Notes

Select this component when designs require switching signals at voltages exceeding standard CMOS limits. Verify that the required on-resistance and leakage specifications align with the application's signal path requirements. Ensure the control logic levels are compatible with the specified input voltage thresholds.

Analog Switches - Special Purpose Part Context

This part belongs to the HV20822 family of high-voltage analog switches. The series is designed for applications requiring robust signal routing under high potential differences. The device integrates latch translators to manage control signals efficiently while maintaining isolation between the high voltage domain and the logic interface.

Analog Switches - Special Purpose Replacement Considerations

Check for direct pin-compatible alternatives within the same product family. Verify that any substitute maintains the same channel count and voltage ratings. Ensure thermal resistance and package dimensions match the existing board layout constraints.
