FPF34892: SIDO Over-Voltage Protection Load Switch

具体说明: The FPF3489x features a Single Input Dual Output (...
  • The FPF3489x features a Single Input Dual Output (SIDO) power switch, which offers surge protection and Over-Voltage Protection (OVP), to protect downstream components and enhancing overall system robustness. Channel one (VBUS to VOUT) is an active-low, 28 V/3.5 A rated, power MOSFET switch with an internal clamp supporting ±100 V surge protection, fixed OVP at 5.8V when OVSEL is tied to GND or 13.9V (FPF34891) / 10.4V (FPF34892) when OVSEL is floating.Channel two (VBUS to BAT) is an active-high, 5 V/6 A rated, power MOSFET, fixed OVP at VBUS is 5.8 V (±200 mV) and Reverse Current Blocking (RCB) during its OFF State. OVLO at BAT can be programmed by external resistors. The Over-Voltage status will be latched and FLAG will signal the fault by pulling low. To re-start this channel from OVLO, EN2 need to be toggled from LOW to HIGH.The FPF3489x is available in a 28-bump, 1.67 mm x 2.96 mm Wafer-Level Chip-Scale Package (WL-CSP) with 0.4 mm pitch.
