Dual 5V and 3.3V μP Power Supply Supervisor with Manual Reset
ASM1834/A/D
rev 1.3
April 2005
Trip Point Tolerance Selection
The 3.3VTOL and 5VTOL inputs allow independent selection of
the reset trip points. If 5VTOL is connected to the 5V supply
input, a 10% tolerance is selected. If 5VTOL is grounded, a 5%
tolerance is selected.
If 3.3VTOL is connected to the 3.3V supply input, a 20%
tolerance is selected. If 3.3VTOL is grounded, a 10% tolerance
is selected. (Refer table below). The 3.3VTOL and 5VTOL
tolerance select inputs should be tied to the ground or to the
respective input supply voltage pin, 3.3V
IN
or 5V
