產品說明
The FP6803 asserts a reset signal whenever the VDD supply voltage declines below the preset threshold and monitors the system voltages from 0.4V to 5V. A time delayed reset can be accomplished with an additional external capacitor. The FP6803 quiescent current is very low and suitable for portable and battery-operated applications.
The output RST signal is set to be active low. RSTremains low for the delay time after reset condition is deasserted and then goes high. The FP6803 provides ±0.5% threshold accuracy for VTH≦3.3V.
FP6803 is available in space-saving SOT-23-6 and TDFN-6 (2mmx2mm) packages.
