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.
