Dual I2C Power
Supply Monitor and
Margining Controller
The LTC®2970 is a dual power supply monitor and
margining controller with an SMBus compatible I2C bus
interface. A low-drift, on-chip reference and 14-bit ΔΣ A/D
converter allow precise measurements of supply voltages,
load currents or internal die temperature. Fault manage-
ment allows ⎯A⎯L⎯E⎯R⎯T to be asserted for configurable over
and under voltage fault conditions. Two voltage buffered,
8-bit IDACs allow highly accurate programming of DC/DC
converter output voltages. The IDACs can be configured
to automatically servo the power supplies to the desired
voltages using the ADC. The LTC2970-1 adds a tracking
feature that can be used to turn multiple power supplies
on or off in a controlled manner.
The bus address is set to 1 of 9 possible combinations by
pin strapping the ASEL0 and ASEL1 pins. The LTC2970/
LTC2970-1 are packaged in the 24-lead, 4mm × 5mm
QFN package.
