SG1549/SG2549/SG3549  
CURRENT SENSE LATCH  
DESCRIPTION  
FEATURES  
Current sensing with 100mV  
threshold  
Common-mode input at ground or  
to 40V  
Complementary outputs  
Automatic reset from PWM clock  
180ns delay  
This monolithic integrated circuit is an analog latch device with digital reset. It was  
specifically designed to provide pulse-by-pulse current limiting for switch-mode power  
supply systems, but many other application are also feasible. Its function is to provide  
a latching switch action upon sensing an input threshold voltage, with reset accom-  
plished by an external clock signal. This device can be interfaced directly with many  
kinds of pulse width modulating control IC's, including the SG1524, SG1525A and  
SG1527A.  
Interface direct to SG1524,  
SG1525A, SG1527A  
The input threshold for the latch circuit is 100mV, which can be referenced either to  
ground or to a wide-ranging positive voltage. There are high and low-going output  
signals available, and both the supply voltage and clock signal can be taken directly  
from an associated PWM control chip.  
HIGH RELIABILITY FEATURES  
- SG1549  
With delays in the range of 200 nanoseconds, this latch circuit is ideal for fast reaction  
sensing to provide overall current limiting, short circuit protection, or transformer  
saturation control.  
Available to MIL-STD-883  
LMI level "S" processing available  
Radiation data available
