HV230GA-G

Analog Switches - Special Purpose Overview

The HV230GA-G is an 8-channel high-voltage analog switch IC utilizing HVCMOS technology. It features integrated bleed resistors to discharge capacitive loads and operates with a logic supply voltage (VDD) ranging from 4.5 V to 13.2 V. The device supports flexible dual high-voltage supplies, typically VPP/VNN combinations such as +40 V/-160 V or +100 V/-100 V. Maximum on-resistance is specified at 30 Ω under standard conditions. The package is a 26-ball fpBGA.

Analog Switches - Special Purpose Feature Summary

• Integrates internal bleed resistors to eliminate voltage buildup on capacitive loads like piezoelectric transducers.
• Includes on-chip 8-bit shift register and latch circuitry for serial data control of the switches.
• Utilizes low charge injection design to minimize signal distortion during switching transitions.

Analog Switches - Special Purpose Applications

• Medical ultrasound imaging systems
• Piezoelectric transducer drivers

Analog Switches - Special Purpose Procurement Notes

Verify component authenticity through authorized Microchip Technology distributors. Confirm that the ordering suffix '-G' indicates lead-free and RoHS compliance status. Ensure the specific fpBGA-26 package variant matches the required footprint for the target PCB layout.

Analog Switches - Special Purpose Selection Notes

Select this component when high-voltage bilateral switching is required alongside low-power CMOS logic control. Verify that the application's peak analog signal current does not exceed the 3.0 A limit per channel. Ensure the operating temperature range aligns with the specified 0°C to 70°C industrial limits.

Analog Switches - Special Purpose Part Context

This part belongs to the Supertex HV series of high-voltage analog switches, now manufactured by Microchip Technology following acquisition. The HV230 specifically addresses applications requiring isolation between low-voltage digital control circuits and high-voltage analog signal paths.

Analog Switches - Special Purpose Replacement Considerations

No direct public substitute part numbers are confirmed in the provided documentation. Evaluate other HVCMOS-based switches only if they match the 8-channel configuration, fpBGA-26 package, and compatible high-voltage supply requirements.
