HV2301PJ-G

Analog Switches - Special Purpose Overview

The HV2301PJ-G is an 8-channel high-voltage analog switch IC manufactured by Microchip Technology, housed in a 28-lead PLCC package. It utilizes HVCMOS technology to combine high voltage bilateral DMOS switches with low power CMOS logic. The device supports flexible operating supply voltages, including VPP/VNN combinations of +40V/-160V, +100V/-100V, and +160V/-40V. Key electrical parameters include a maximum on-resistance of 38 ohms at VPP=+40V/VNN=-160V, a typical off-isolation of -60dB at 5MHz, and a quiescent power dissipation of 10µA. It features integrated bleed resistors and operates within a temperature range of 0°C to 70°C.

Analog Switches - Special Purpose Feature Summary

• Integrated bleed resistors on outputs to eliminate voltage buildup on capacitive loads
• Cascadable serial data register with latches for efficient control
• HVCMOS technology providing high performance and excellent noise immunity
• Low charge injection characteristics suitable for precision applications

Analog Switches - Special Purpose Applications

• Medical ultrasound imaging
• NDT metal flaw detection
• Piezoelectric transducer drivers
• Inkjet printer heads
• Optical MEMS modules

Analog Switches - Special Purpose Procurement Notes

Verify the specific package type required for the design, as the HV2301 family includes both 48-lead LQFP (FG) and 28-lead PLCC (PJ) options. Confirm RoHS compliance status, indicated by the suffix '-G', against current environmental regulations. Ensure that the ordering documentation explicitly references the PJ package variant to avoid confusion with the FG version. Cross-reference the manufacturer's latest datasheet for any potential pinout or marking changes.

Analog Switches - Special Purpose Selection Notes

Select the HV2301PJ-G when a 28-lead PLCC footprint is necessary for the PCB layout. This component is appropriate for designs requiring high voltage switching controlled by low voltage logic signals. Consider the on-resistance variations across different supply voltage configurations during circuit simulation. Verify that the application does not exceed the peak analog signal current limits specified in the absolute maximum ratings.

Analog Switches - Special Purpose Part Context

The HV2301PJ-G belongs to the HV2301 series of enhanced analog switches. It serves as an upgrade to the earlier HV232 model, offering improved performance characteristics. The device is part of a broader family that includes variants with different package options, such as the HV2301FG-G in a 48-lead LQFP. All variants share the same core functionality and electrical specifications.

Analog Switches - Special Purpose Replacement Considerations

The HV2301FG-G is a direct functional equivalent available in a 48-lead LQFP package. Designers must account for the physical footprint differences between the PLCC and LQFP packages if substituting components. No other cross-model replacements are documented in the official datasheet.
