Typical Operating Configuration
Description
The H6052 is a CMOS device whichmonitors the supply voltage
and controls the reset of the microprocessor. Upon the supply
voltage rising above V_{TH ON}, the reset output, whether RES or
RES, will remain active (RES = 1, RES = 0) for an additional 160
ms. This allows the system voltage and the oscillator of the
microprocessor system to stabilize before the system becomes
fully active. When V_DD drops below V_{TH OFF}, the reset output
goes active (RES = 1, RES = 0).
Applications
All microprocessor and microcontroller applications where an
automatic restart of the micreoprocessor after power down is
required:
n White goods
n Brown goods
n Automotive electronics
n Industrial electronics
