Controller IC Chip - MOSFET G5934HZ G5934 chip for laptop- Integrated portable calculator chip(SKU.1-CHIP0460)
High Voltage 1.5x Charge Pump with Load Switch Controller
The G5934 is a high-voltage switched-capacitor charge pump that provides the regulated output volt-age of 1.5x input voltage. Input voltages ranging from 8V to 24V can be converted into a 12V to 36V output supply. The device is ideal for battery-powered con-version applications in notebook computers with a typical operating current of 150mA at 8V supply and 190mA at 24V supply. The G5934 has a NMOS open-drain output pin for power good indication. When VOUT > 1.5 x VIN x 90%, the NMOS will be turned off immediately and PG pin will be pulled high by external resistor. The G5934 contains an embedded 12-V LDO to pro-vide the supply voltage to the drivers controlled by ON signals. The discharging networks are connected to the 22Ω resistor to shut down the low-voltage system while control input signals ON are not ready. The G5934 contains an over-temperaturecircuit to protect the device under continuous output short cir-cuit conditions. The G5934 is available in TQFN3X3-20 package (thermal pad included).
