HV2605BD-M936

Analog Switches - Special Purpose Overview

The HV2605BD-M936 is a 16-channel high-voltage analog switch integrated circuit manufactured by Microchip Technology. It utilizes HVCMOS technology to combine bilateral DMOS switches with low-power CMOS logic, enabling control of high-voltage signals via low-voltage inputs. The device features a 42-ball bumped die package and supports dual supply voltages ranging from -160 V to +160 V. Key electrical parameters include a maximum on-resistance of 25 Ohms, a quiescent current of 10 µA, and a data shift clock frequency up to 20 MHz. Operating temperatures range from 0°C to +70°C.

Analog Switches - Special Purpose Procurement Notes

Verify the specific suffix BD-M936 against official Microchip documentation to confirm the 42-ball bumped die configuration and reel packaging details. Ensure compatibility with surface-mount assembly processes suitable for bumped die components. Cross-reference the datasheet revision DS20005498C for any updates regarding pin functions or thermal characteristics before finalizing procurement specifications.

Analog Switches - Special Purpose Selection Notes

Select this component when designing circuits requiring high-voltage analog switching with low distortion and low power consumption. The HV2605 variant lacks internal bleed resistors, making it distinct from the HV2705; choose based on whether external discharge paths are required for capacitive loads. Confirm that the 42-ball bumped die package fits the target PCB layout constraints and assembly capabilities.

Analog Switches - Special Purpose Part Context

This part belongs to the HV2605/HV2705 family of 16-channel low harmonic distortion high-voltage analog switches. The HV2605 model specifically omits the integrated bleed resistors found in the HV2705 counterpart. Both variants share identical switching performance and control logic but differ in output handling for capacitive loads like piezoelectric transducers.

Analog Switches - Special Purpose Replacement Considerations

The HV2705BD-M936 serves as a functional substitute if integrated bleed resistors are desired for discharging capacitive loads. For leaded package alternatives, consider the HV2605FG-G (LQFP) or HV2605TQ (TQFP), noting that the LQFP package is not recommended for new designs per manufacturer guidelines.

Analog Switches - Special Purpose FAQ

Does the HV2605BD-M936 include integrated bleed resistors?

No, the HV2605 does not have integrated bleed resistors. This feature is exclusive to the HV2705 variant within the same family.

What is the maximum data shift clock frequency?

The device supports a data shift clock frequency of up to 20 MHz.

How is the latch enable function managed to reduce noise?

To minimize clock feed-through noise, the latch enable bar should remain high until all bits are clocked into the shift register. Data is latched on the rising edge of the latch enable signal.
