LTC2970/LTC2970-1

Dual I C Power

Supply Monitor and

Margining Controller

DESCRIPTIO

FEATURES

The LTC^®2970 is a dual power supply monitor and

margining controller with an SMBus compatible I C bus

■

Less Than ±±0.5 Total Unadjusted Error 14-Bit ΔΣ

ADC with On-Chip Reference

■

Dual, 8-Bit IDACs with 1x Voltage Buffers

interface. A low-drift, on-chip reference and 14-bit ΔΣ A/D

converterallowprecisemeasurementsofsupplyvoltages,

load currents or internal die temperature. Fault manage-

ment allows ALERT 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.

■

Linear, Voltage Servo Adjusts Supply Voltages by

Ramping IDAC Outputs Up/Down

■

I C™ Bus Interface (SMBus Compatible)

■

Extensive, User Conﬁgurable Fault Monitoring

■

On-Chip Temperature Sensor

■

Available in 24-Lead 4mm × 5mm QFN Package

Programmable Reference

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.
