From 369039fe52dc59c7e80c003a12cbaefd8a00abe9 Mon Sep 17 00:00:00 2001 From: Keith Packard Date: Sat, 27 Jul 2019 16:54:33 -0700 Subject: [PATCH] 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.
