GMT致新 G509L30DP81G 電源開關(guān)芯片

General Description

The G509 is an integrated power switch for self-powered and bus-powered Universal Serial Bus (USB) applications. G509xxxxT11G and G509x25DTB1G are 67mΩ RDS(ON). In addition, G509N02DT73G is 120mΩ RDS(ON). Moreover, G509x3xDxx1G is 37mΩ RDS(ON). Several Protection features include current limiting and thermal shutdown to prevent catastrophic switch failure caused by increasing power dissipation when continuous heavy loads or short circuit occurs. A built-in charge pump is used to drive the N-channel MOSFET that is free of parasitic body diode to eliminate any reversed current flow across the switch when it is powered off. When the output voltage is higher than input voltage, the power switch is turned off by internal output reverse protection comparator.

OC is an open-drain output report over-current or over-temperature event and has typical 9ms deglitch timeout period. In addition, output reverse protection occurs with typical 5ms (1.25ms) deglitch timeout period in G509xxxxT11G, G509x1SDTB1G, and G509N02DT73G (G509x3xDxx1G).
