Figure 15 – Low Voltage Microprocessor Reset
A time delayed reset can be accomplished with the addition
of CDLY. For systems with extremely fast power supply rise
times (<500ns) it is recommended that the RCDLY time
constant be greater than 5.0µs. VTH(MPU) is the

Figure 18 – MOSFET Low Voltage gate Drive Protection
Figure 17 – Voltage Monitor
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 4.6 volt threshold
of the MC34064, its output grounds the gate of the L2
MOSFET.

Figure 19 – Low Voltage Microprocessor Reset with
Additional Hysteresis.
Comparator hysteresis can be increased with the addition of resistor RH. The hysteresis equation has been simplified and does
not account for the change of input current IIN as VCC crosses the comparator threshold. An increase of the lower threshold.
∆VTH(LOWER) will be observed due to IIN which is typically 340μA at 4.59V. The equations are accurate to ±10% with RH less
than 150ꢀ and RL between 1.5kꢀ and 10kꢀ.
