15.0 Application Notes
15.1 Chip Global Reset Recommend Circuit
To ensure a proper reset pulse can be applied to /RESET pin (pin 27) to complete the power-on reset,
the recommend reset circuit is to connect the AL440B /RESET pin (pin 27) to V
DD
with a 2k
resistor and to Ground with a 10
μ
f capacitor as follows.

It is also recommend adding buffers for the power-on reset circuit to increase the driving capability
for any application with multiple AL440B chips.
