Application Examples
High and Low-Side Current Sensing across Shunts
Explore the block diagram to see how, in a Battery Management System (BMS), current sense amplifiers measure the tiny voltage drop across a low resistance shunt resistor placed in the battery path to precisely calculate real time current flow. This measurement is critical for tracking the battery’s State of Charge (SoC) and ensuring the system stays within safe limits by detecting overcurrent or short circuit conditions.
Instrumentation & Medical Diagnostics
Zero drift architectures in onsemi’s precision Op Amps are designed to maintain high accuracy and stability over wide temperature ranges and long operating periods. Open the block diagram to see suitable zero drift amplifiers that help to eliminate offset voltage and thermal drift in medical and lab equipment, ensuring tiny physiological or chemical signals, such as ECG or blood glucose measurements, remain accurate and stable over time.
Over-current Protection Using a Fast Comparator
In a Solid State Circuit Breaker, explore the block diagram to understand how a fast comparator acts as an instantaneous electronic trip, continuously comparing shunt voltage to a safe limit. This allows it to shut down power transistors in a short period of time before an overcurrent spike can destroy the hardware.
