Latch-up Considerations
As with any CMOS IC, the potential exists for latch-up
if signals are applied to the device which are outside
the power supply range. This is of particular concern
during power-up if the external circuitry (such as the
sensor network, V
MIN
divider or shutdown circuit) is
powered by a supply different from that of the TC642.
Care should be taken to ensure that the TC642’s V
DD
supply powers up first. If possible, the networks
attached to V
IN
and V
MIN
should connect to the V
DD
supply at the same physical location as the IC itself.
Even if the IC and any external networks are powered
by the same supply, physical separation of the
connecting points can result in enough parasitic
capacitance and/or inductance in the power supply
connections to delay one power supply “routing” versus
another.
