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

(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.
