Description
The GN809 family allows the user to customize the CPU reset function without any external components. The
user has a large choice of reset voltage thresholds and output driver configurations, all of which are preset at
the factory. Each wafer is trimmed to the customer’s specifications.
These circuits monitor the power supply voltage of up based systems. When the power supply voltage drops
below the voltage threshold a reset is asserted immediately (within an interval TD1). The reset remains asserted
after the supply voltage rises above the voltage threshold for a time interval, TD2. The reset output is active low
(RESETB). The reset output may be configured as either push/pull or open drain. The state of the reset output
is guaranteed to be correct for supply voltage greater than 1V.
Space saving SOT-23 package and micropower quiescent current (<3.0uA) make this family a natural for
portable battery powered equipment.
