HV7801K1-G Description

Short technical summary and product information.

The HV7801K1-G from Microchip Technology is a high-side current monitor IC that transfers a high-side current measurement voltage to its ground-referenced output with a voltage gain of five. This device is suitable for applications requiring precise current monitoring, such as Switched-Mode Power Supplies (SMPS), battery monitoring, and motor control.

 

Key features include a wide supply voltage range from 8V to 450V, a maximum VSENSE of 500mV, and a typical gain of 5.0±1%. The IC boasts a low quiescent current of only 50µA, making it ideal for battery-powered and portable applications. It offers fast rise and fall times, ranging from 700ns to 2.0µs, ensuring responsive performance.

 

The HV7801K1-G is available in a compact 5-lead SOT-23-5 (SC-74A, SOT-753) surface-mount package. Its design emphasizes ease of use, low component count, and low cost, contributing to efficient system integration.

 

This current monitor IC is well-suited for offline, battery, and portable applications due to its wide input voltage range and low power consumption. The high accuracy of its transfer ratio and small size further enhance its utility in space-constrained designs.
