Working Principle
Inverting input stage drives a bipolar totem-pole output stage capable of sourcing/sinking 6A peak. The low output impedance (2 ohm source, 2 ohm sink) enables fast gate charge/discharge. Under-voltage lockout prevents partial turn-on of external MOSFET. Input logic threshold is compatible with both TTL and CMOS levels.
Applications
- Switch-mode power supply gate drive
- Motor drive half-bridge
- LED driver MOSFET drive
- Solar micro-inverter
