HV2601BD-M936

Analog Switches - Special Purpose Overview

The HV2601BD-M936 is a low-charge injection, 16-channel high-voltage analog switch IC manufactured by Microchip Technology. It utilizes High-Voltage CMOS technology to combine bilateral DMOS switches with low-power CMOS logic. The device accepts serial data into a 16-bit shift register and latches it for independent control of each channel. It operates with flexible dual supplies ranging from +40V/-160V to +160V/-40V, controlled by 3.3V logic levels. Key electrical characteristics include an on-resistance of 25 Ohms at VPP=+40V/VNN=-160V, a small signal bandwidth of 50 MHz, and very low quiescent power dissipation.

Analog Switches - Special Purpose Feature Summary

• Serial data shifting and latching mechanism for efficient multi-channel control
• High-voltage CMOS technology enabling operation with large differential supply voltages
• Low charge injection and parasitic capacitance for signal integrity

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 BD-M936 against official Microchip documentation to confirm package type and tape/reel specifications. Ensure compatibility with existing design files regarding pinout and thermal requirements. Cross-reference the datasheet revision date to validate all electrical parameters before finalizing procurement orders.

Analog Switches - Special Purpose Selection Notes

Select this component when designing circuits requiring high-voltage analog switching controlled by low-voltage digital signals. It is suitable for applications demanding low charge injection and high isolation. Consider the HV2701 variant if integrated bleed resistors are required to prevent voltage build-up on capacitive loads such as piezoelectric transducers.

Analog Switches - Special Purpose Part Context

The HV2601BD-M936 belongs to the HV2601/HV2701 family of low-charge injection, 16-channel high-voltage analog switches. This series is designed for specialized applications involving piezoelectric transducers and medical imaging. The BD suffix typically denotes the bumped die package configuration, distinguishing it from the LQFP or TQFP packaged versions within the same functional family.

Analog Switches - Special Purpose Replacement Considerations

The HV2701BD-M936 is a direct functional substitute within the same package, differing only by the inclusion of integrated output bleed resistors. Verify that the absence of bleed resistors in the HV2601 does not impact the specific load requirements of the target application.
