Figure 11. Voltage Monitor

Figure 12. Solar Powered Battery Charger

Figure 13. Low Power Switching Regulator

Figure 14. MOSFET Low Voltage Gate Drive Protection

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 V threshold of the MC34064, its output grounds the gate of the L2

MOSFET.
