EM MICROELECTRONIC - MARIN SA Reset Circuit with Fixed Delay Description The EM6353 is an ultra-low current reset circuit available in a large variety of configurations and very small packages for maximum flexibility in all end-applications up to 125°C and using power supplies between 1.5V and 5.5V. This circuit monitors the supply voltage of any electronic system, and generates the appropriate reset signal after a fixed reset timeout period. The threshold defines the minimum allowed voltage which guarantees the good functionality of the system. When VDD rises above VTH, the output remains active for an additional delay time. This allows the system to stabilize before getting fully active. The EM6353 features three output types: active-low pushpull, active-low open-drain and active-high push-pull. Small SC70-5L and SOT23-3L packages as well as ultra-low supply current of 2.9µA make the EM6353 an ideal choice for portable and battery-operated devices. EM6353 Features ! ! ! ! ! ! 200ms reset timeout period (25ms on request) Ultra-low supply current of 2.9µA (VDD=3.3V) Operating temperature range: -40°C to +125°C ±1.5% reset threshold accuracy 11 reset threshold voltages VTH: 4.63V, 4.4V, 3.08V, 2.93V, 2.63V, 2.2V, 1.8V, 1.66V, 1.57V, 1.38V, 1.31V 3 reset output options: " Active-low RESET push-pull " Active-low RESET open-drain " Active-high RESET push-pull No external components Immune to short negative VDD transients Guaranteed Reset valid down to 0.8V Threshold hysteresis: 2.1% of VTH Very small SOT23-3L and SC70-5L packages ! ! ! ! !
