HV2701TQ-G-M931

Analog Switches - Special Purpose Overview

The HV2701TQ-G-M931 is a low-charge injection, 16-channel high-voltage analog switch manufactured by Microchip Technology. It utilizes High-Voltage CMOS technology to combine bilateral DMOS switches with low-power CMOS logic. The device features integrated bleed resistors on the outputs to eliminate voltage build-up on capacitive loads. It operates with flexible supply voltages, including VPP/VNN combinations of +40V/-160V, +100V/-100V, and +160V/-40V. The unit is housed in a 48-lead TQFP package.

Analog Switches - Special Purpose Feature Summary

• Integrated bleed resistors on all outputs to prevent voltage accumulation on capacitive loads
• Low-charge injection design for minimal signal distortion during switching
• Cascadable serial data register with latches for efficient control
• Compatible with 3.3V input logic levels

Analog Switches - Special Purpose Applications

• Medical ultrasound imaging systems
• Non-destructive testing (NDT) metal flaw detection
• Piezoelectric transducer drivers
• Optical MEMS modules

Analog Switches - Special Purpose Procurement Notes

Verify the specific suffix M931 against official Microchip documentation to confirm tape-and-reel packaging specifications. Ensure the ordering part number matches the required 48-lead TQFP package variant. Cross-reference the datasheet revision to confirm current manufacturing status and any recent product change notifications affecting this specific marking code.

Analog Switches - Special Purpose Selection Notes

Select the HV2701 over the HV2601 when integrated output bleed resistors are required to discharge capacitive loads such as piezoelectric transducers. Confirm that the operating voltage range fits within the recommended VPP and VNN limits. Verify that the 48-lead TQFP package meets the thermal and spatial constraints of the target PCB layout compared to legacy LQFP options.

Analog Switches - Special Purpose Part Context

This component belongs to the HV2601/HV2701 family of high-voltage analog switches. The HV2701 variant is distinguished by its built-in bleed resistors, whereas the HV2601 lacks this feature. Both share identical pinouts and control logic but differ in output stage configuration. The TQFP package is the recommended alternative to the legacy LQFP for new designs.

Analog Switches - Special Purpose Replacement Considerations

The HV2601TQ-G serves as a functional substitute if integrated bleed resistors are not required in the application circuit. Verify that the absence of internal bleed paths does not cause voltage drift issues on the connected load.
