Pulse-By-Pulse Current Limiting Referring to Figure 5, Equation 1 determines the peak current, Is. (1) 8.3.7 Shutdown UC1856-SP incorporates a shutdown pin (pin16). Shutdown threshold voltage is 1 V. Exceeding the shutdown threshold voltage causes the device to shutdown. • If current into ICL_SS VREF/R1 > 3-mA SCR holding current (minimum latch current), then the device latches off. Power recycle is required to un-latch the device. • If VREF/R1 < 0.8 mA, that is ICL_SS < 0.8 A, then this ensures that the circuit does not latch in a shutdown state. Figure 6.
