is a small, low RON, signal-channel power-distribution switch with
controlled turn-on slew rate. The device contains a N-channel MOSFET that can
operate over an input voltage range of 2.8V to 16V and can support a maximum
continuous current of 3A. Externally programmable rising time control helps to
minimize input inrush current during start-up.
wide input voltage range of the switch makes JW7112 versatile solution for many
different voltage rails. The EN pin controls ON/OFF for each JW7112
distribution switch, so one DC/DC converter can deliver power to several
requirements and total power efficiency is maximized. JW7112 provide a complete
protection solution, including current-limit protection, short-circuit
protection (SCP), over-temperature protection (OTP) and under voltage lockout
protection (UVLO). The device offers a programmable current-limit threshold via
an external resistor.
JW7112 integrates a50Ωpull-down resistor for quick output
discharge when the switch is turned off.
