Applied voltage maximum ±225 V to ground
All-Off state.
+25° C, V_SW (differential) = ±320 V
+85° C, V_SW (differential) = ±330 V
-40° C, V_SW (differential) = ±310 V
I_SW(on) = ±10 mA, ±40 mA

Per SW1 & SW2 On Resistance test
conditions.
V_SW (on) = ±10 V, +25° C
V_SW (on) = ±10 V, +85° C
V_SW (on) = ±10 V, -40° C
Break switches on, all other switches off.
Apply ±1 kV 10x1000 μs pulse with
appropriate protection in place.
+25° C, Logic inputs = gnd,
V_SW (T_LINE, R_LINE) = ±225 V

+85° C, Logic inputs = gnd,
V_SW (T_LINE, R_LINE) = ±225 V
V_SW (T_BAT, R_BAT) = ±225 V
-40° C, Logic inputs = gnd,
V_SW (T_LINE, R_LINE) = ±225 V
V_SW (T_BAT, R_BAT) = ±225 V
