TYPICAL APPLICATION CIRCUITS
FIGURE 13. — LOW VOLTAGE MICROPROCESSOR RESET.
A time delayed reset can be accomplished with the addition of C
DLY.
For systems with extremely fast power supply rise times (< 500ns) it
is recommended that the RC
DLY time constant be greater than 5.0s.
V
TH(MPU) is the microprocessor reset input threshold.
Overheating of the logic level power MOSFET due to insufficient gate
voltage can be prevented with the above circuit. When the input signal is
below the 4.3 volt threshold of the LX7001C, its output grounds the gate
of the L2 MOSFET.
