4 years agoSwitch pyro series resistors to 1k
Keith Packard [Sun, 28 Jul 2019 00:06:08 +0000 (17:06 -0700)]
Switch pyro series resistors to 1k

This limits the current through the comparator to 3.3mA when it fires
to make sure the gate voltage on the FET is low enough. The SI LM293
comparators are rated at 4mA current, unlike the TI parts which are
rated at 6mA, hence the move from 549 to 1k.
