  • Description

    JW®7112 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.

    The 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.

    The JW7112 integrates a50Ωpull-down resistor for quick output discharge when the switch is turned off.
