Description

This single–supply, low–side, current sensing solution accurately detects load current up to 1A and converts it to a voltage between 50mV and 4.9V. The input current range and output voltage range can be scaled as necessary and larger supplies can be used to accommodate larger swings.

Features
  • Senses Temperature between 25°C - 50°C 
  • Output: 0.05V - 3.25V 
  • Single 3.3V Supply with half-supply reference
