linear DESIGN FEATURES LTMag-V18N01-02-LTC4151-Z_Hou service manual
The LTC4151 and LTC4151-1 are fully featured, rugged solutions for accurate high-side current sensing and supply voltage monitoring. These devices combine a precision high-voltage amplifier, level shift circuit, voltage divider, 12-bit ADC, and I2C interface into a single IC available in MS10 or DFN-10 packages.
The chips support operation from 7V to 80V with absolute maximum ratings of 90V. They offer high accuracy over the industrial temperature range and can be configured for continuous scanning at 7.5Hz or snapshot mode. The LTC4151 includes a shutdown pin for power saving, while the LTC4151-1 features split SDA pins to facilitate simple optoisolation schemes.
