Chip Description
The EG1168 is a cost-effective, multi-functional driver chip for half-bridge and push-pull power supplies. It integrates a 5V linear power supply, operational amplifier, MOSFET peak current protection, VCC undervoltage protection, VB undervoltage protection, two symmetrical half-bridge and push-pull PWM outputs, a latch circuit, a level shift circuit, a pulse filter circuit, and an output driver circuit. It is ideal for use in digital half-bridge power supplies and digital push-pull power supplies.
The EG1168 has a high-end operating voltage of up to 600V and a wide low-end Vcc supply voltage range of 10V～20V, with a VCC static power consumption of less than 1.5mA. The chip has a latch function to prevent simultaneous conduction of the output power transistors. The input channel PWMIN has a built-in 200K pull-down resistor, which keeps the upper and lower power MOSFETs off when the input is floating. The output current capability is IO+/- 2A/2.5A, and it uses a SOP16 package.
