From a9052c6a6b556764ad98cf8647cde889b45c6376 Mon Sep 17 00:00:00 2001 From: Dennis Brentjes Date: Fri, 2 Oct 2026 09:06:44 +0000 Subject: [PATCH] Rework the eFuse schematic for readability; 3-resistor OVLO divider Redraws the eFuse area with proper wires instead of labels-on-pins, and simplifies the divider that 228ff03 added. The first draft split R3 into 12 k + 2.2 k to hit 14.2 k, purely to preserve the original ~8.9 V UVLO. That bought a fourth resistor and a named junction net (EFUSE_R3MID) that nothing else touched. The ~9 V UVLO turned out to be an assumption carried over from the original design rather than a requirement: U3's minimum input is 4.5 V, so relaxing it to 6.78 V costs nothing and is in fact less likely to chatter if the GC rail sags. R46 620 k -> 100 k (C25741) R1: 12V_RAW -> EN/UVLO R47 100 k -> 12.4 k (C11692) R2: EN/UVLO -> OVLO R48 NEW 10 k (C25744) R3: OVLO -> GND R49 removed R45 100 k -> 33 k (C25779) ILIM 0.52 A -> 1.52 A OVLO is unchanged at 15.18 V typ (14.47-15.78 worst case) against U3's 17 V limit, so the simplification costs nothing on the parameter that matters. Verified: 12V_RAW(R46.2) / EFUSE_EN(R46.1,R47.1,U13.5) / EFUSE_OVLO(R47.2, R48.1,U13.2) / GND(R48.2,R45.2,U13.4); 152 -> 151 components with only R49 removed; ERC 0 violations.
