LTC4211MS Figure 17 shows a 12V, 3A Hot Swap application circuit. The resistor divider R1/R2 programs the undervoltage lockout externally and allows the system to start up after V CC increases above 9.46V. The resistor divider R3/R4 monitors V OUT and signals the RESET pin when V OUT goes above 10.54V. Transient voltage suppressor Z1 and snubber network (C X , R X ) are highly recommended to protect the 12V applications system from ringing and voltage spikes. R G is recommended for V CC > 10V and it can minimize high frequency parasitic oscillations in the 0755-82713782, 13590238352黃小姐。
