SY6818PLC中文资料集成反向阻断FET的大电流过压保护开关数据手册Silergy规格书

描述 Description

SY6818 is an over voltage protection switch with high current capability to prevent damage to the downstream system with low voltage rating. It achieves wide input voltage range from 2.5VDC to 30VDC. Programmable OVP is available with simple external resistor divider. Integrated reverse blocking FET up to 20V rating prevents the leakage current from output side to input side when the input power supply is removed, but without output discharging. Extremely low power path resistance RPWPT helps to reduce power loss during the normal operation. Enable control is available to cut off the energy path. High accuracy current indicator is employed internally. It integrates the over-temperature protection shutdown and auto-recovery with hysteresis to protect against over temperature events. It has a default over current protection up to 5A internally and auto-recovery. Each auto-recovery process is composed of deglitch time TDG and switch turn-on time TON. This IC along with CSP-12, 1.73mmx1.73mm footprint provides small PCB area application.
