OPERATION  
TheLTC4151/LTC4151-1accuratelymonitorhighsidecur-  
rent and voltages. These devices accept a wide range of  
input voltages from as low as 7V up to 80V and consume  
less than 1.7mA quiescent current in normal operation. A  
shutdown mode is available with the LTC4151 to reduce  
the quiescent current to less than 300μA by pulling the  
SHDN pin below 1V.  
In snapshot mode, the LTC4151/LTC4151-1 can perform  
on-demand measurement of a selected voltage without  
the need of continuous polling by a master controller. The  
snapshot mode is enabled by programming the control

register through the I C interface. A status bit in the data  
registermonitorstheADC’sconversion. Whentheconver-  
sion is completed, the 12-bit digital code of the measured  
voltage is held in the corresponding data registers.  
In default continuous scan mode after power-up, the

The LTC4151/LTC4151-1 provide an I C interface to read  
ously and sequentially measures the high side differen-  
the ADC data from the data registers and to program the  
control register. Two three-state pins, ADR0 and ADR1,  
are used to decode nine device addresses (see Table 1).  
The LTC4151 features a single SDA pin to handle both  
input data and output data, while the LTC4151-1 provides  
separate SDAI (input) and SDAO (inverted output) pins to  
facilitate optoisolation.
