HV20822TQ-G

Analog Switches - Special Purpose Overview

The HV20822TQ-G is a high-voltage analog switch IC manufactured by Microchip Technology, utilizing Supertex HVCMOS technology. It integrates sixteen 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 standards. Key electrical parameters include a typical on-resistance of 22Ω, a maximum turn-on/turn-off time of 5µs, and a quiescent current consumption of 10µA. It is housed in a 48-lead LQFP package.

Analog Switches - Special Purpose Procurement Notes

Verify the specific ordering suffix against official documentation to confirm packaging details such as reel or tray quantities. Confirm RoHS compliance status and lead-free designation through the manufacturer's latest datasheet or product change notifications before finalizing procurement specifications.

Analog Switches - Special Purpose Selection Notes

Select this component when designing circuits requiring high-voltage analog signal routing controlled by standard low-voltage logic interfaces. Ensure the application voltage does not exceed the absolute maximum ratings of +225V across the supply rails. Verify that the thermal resistance characteristics of the 48-lead LQFP package align with the system's heat dissipation capabilities.

Analog Switches - Special Purpose Part Context

This component belongs to the HV20822 family of high-voltage analog switches originally developed by Supertex Inc., which was subsequently acquired by Microchip Technology. The series is designed specifically for applications demanding reliable switching of high-voltage signals using low-power control logic, bridging the gap between standard microcontrollers and high-voltage loads.
