Product Number: LTC7000A
I have been experiencing issues with the LTC7000 mosfet driver. It is used as a static switch driver in a failsafe system for depowering an electronic speed controller. What happens is that over some extended use the driver will no longer fully enhance the MOSFET, only getting about half the intended gate voltage. The connected ESC is driving a moderately sized motor load at 11-13A and about 8V. So far i am suspecting that it might be because we lack a diode at the TS pin, but please do tell me if there are other obvious issues.
Attached are pictures of the schematic we used, as well as the PCB design:
