Note 2. At higher input voltages, a dissipation limiting resistor, R

G , is required. See Figure 1.

RECOMMENDED OPERATING CONDITIONS (Note 3)

ELECTRICAL CHARACTERISTICS

(Unless otherwise specified, these specifications apply over the operating ambient temperatures for SG1544 with -55

°C ≤ T

A ≤ 125°C,

SG2544 with

-25

°C ≤ T

A ≤ 85°C, SG3544 with 0°C ≤ TA ≤ 70°C, and +VIN = 10V. Indicator outputs have 2kΩ pull-up resistors. All electrical ratings and specifications

are tested with the inverting over-voltage input and the non-inverting under-voltage input externally connected to the 2.5V reference. Low duty cycle

testing techniques are used which maintains junction and case temperatures equal to the ambient temperature.)

THERMAL DATA

Note A. Junction Temperature Calculation: T

J = TA + (PD x θJA).

Note B. The above numbers for

JC are maximums for the limiting

thermal resistance of the package in a standard mount-

ing configuration. The

JA numbers are meant to be

guidelines for the thermal performance of the device/pc-

board system. All of the above assume no ambient

airflow.
