Confidential-prepared for Customer Use Only 7 AN_SY6288 Operation The SY6288 is a current limited P-channel MOSFET power switch designed for high-side load-switching applications. There is no parasitic body diode between drain and source of the MOSFET, so the SY6288 prevents current flow from out to input when out being externally forced to a higher voltage than VIN when chip is disabled. Over-current protection When the over-current condition is sensed, the gate of the pass switch is modulated to achieve constant output current. Under output short circuit conditions, the normal current limit folded back 50%. If the over current condition persists for a long enough time, the junction temperature may exceed 150°C, and overtemperature protection will shut down the part. Once the chip temperature drops to 130°C, the part will restart. Fault Flag (OCB) The OCB output is asserted (active low) when an over temperature shutdown condition is encountered. The OCB will also be pulled if over current or reverse blocking happens and persists for 10ms. The output remains asserted until the fault status is removed. Connecting a heavy capacitive load to an enabled device can cause a momentary over current condition; however, no false reporting on OCB occurs due to the 10-ms deglitch circuit. OCB is not deglitched when the switch is turned OFF due to an over temperature shutdown. Supply Filter Capacitor In order to prevent the input voltage drooping during hot-plug events, a 10uF ceramic capacitor form VIN to GND is strongly recommended. However, higher capacitor values could reduce the voltage droop on the input further. Furthermore, an output short will cause ringing on the input without the input capacitor. It could destroy the internal circuitry when the input transient exceeds 6V which is the absolute maximum supply voltage even for a short duration. Output Filter Capacitor Between VOUT and GND, a low-ESR 150uF aluminum electrolytic or tantalum capacitor is strongly recommended to meet the 330mV maximum droop requirement. Standard bypass methods should be used to minimize inductance and resistance between the bypass capacitor and the down steam connector. This will reduce EMI and improve the transient performance. If long cables are connected to the output terminals, an anti-parallel schottky diode such as BAT54 is suggested to be placed in parallel with the output terminals to absorb the negative ringing due to the cable inductance. PCB Layout Guide For best performance of the SY6288, the following guidelines must be strictly followed: Locate the ceramic bypass capacitors as close as possible to the VIN pins and VOUT pins of SY6288. Keep all VBUS traces as short and wide as possible and use at least 2 ounce copper for all VBUS traces. Place a ground plane under all circuitry to lower both resistance and inductance and improve DC and transient performance. A low-ESR 150uF aluminum electrolytic or tantalum capacitor between VOUT and GND is strongly recommended. Locate the output capacitor as close to the connectors as possible to lower impedance (mainly inductance) between the port and the capacitor and improve transient performance. Input and output capacitors should be placed closed to the IC and connected to ground plane to reduce noise coupling. AN_SY6288 Rev.1.0 PCB Layout Guide (SO8) Silergy Corp.
