5.3 Power Up Sequence
The ZL30110 requires that the 3.3 V supply is not powered up after the 1.8 V supply. This is to prevent the risk of
latch-up due to the presence of protection diodes in the IO pads.
Two options are given:
1. Power-up the 3.3 V supply fully first, then power up the 1.8 V supply
2. Power up the 3.3 V supply and the 1.8 V supply simultaneously, ensuring that the 3.3 V supply is never lower
than a few hundred millivolts below the 1.8 V supply (e.g., by using a schottky diode or controlled slew rate)
5.4 Reset Circuit
A simple power up reset circuit with about a 60
μ
s reset low time is shown in Figure 6. Resistor R
P
is for protection
only and limits current into the RST pin during power down conditions. The reset low time is not critical but should
be greater than 300 ns.
