NOTES:
1. The output current ITXO + ITXOX is adjustable by the external resistor R546. ITXO + ITXOX = 10 * IR546, IR546 = VR1/R546,
2. Thresholds are independent of supply voltages. Thus the SA1620 is compatible with SA1638 and with the power down inputs of usual
external voltage regulators.
3. PON logic 1 max is VBATT.
