I'm ultimately trying to make a BLDC motor driver, but in the meantime I'm trying to get the IRS2301 MOSFET driver I intend to use working as expected. I built an H-bridge test circuit with a 1K resistor as my simulated load (shown below), and started with both drivers' HIN and LIN pins grounded, when I do this, the gate and source on both high side FETs read 10V, but are not shorted when do a connectivity test. The low side gates read 0V, as expected, but I cannot seem to get the high side gates to operate correctly with the driver. I've modeled my circuit based on AN-978, and cannot figure out why even the most basic operation isn't working, so any advice would be appreciated.
It is the bias current for the pulse generator circuitry in the high side part of the driver causing the DC voltage reading, as with the bottom FETs turned off there is no path to GND, other than the 100k resistors. Turn the bottom FETs on and I believe the problem will go away.
