SG2549M

High-Reliability Current Sense Latch;

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 applications are also feasible.? Its function is to provide a latching switch action upon sensing an input threshold voltage, with reset accomplished 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.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.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.??ROHS
