Functional Description
The MIC2213 is a high performance, low quiescent current
power management IC consisting of two
μ
Cap low dropout
regulators, a power-on reset (POR) circuit and an open-drain
driver. The first regulator is capable of sourcing 150mA at
output voltages from 1.25V to 5V. The second regulator is
capable of sourcing 300mA of current at output voltages from
1.25V to 5V. The second regulator has a POR circuit that
monitors its output voltage and indicates when the output
voltage is within 5% of nominal. The POR offers a delay time
that is externally programmable with a single capacitor to
ground. An open-drain driver completes the power manage-
ment chipset, offering the capability of driving LEDs for
keypad backlighting in applications such as cellphones.
Enable
The enable input allows for logic control of both output
voltages with one enable input. The enable input is active
high, requiring 1.8V for guaranteed operation. The enable
input is CMOS logic and cannot by left floating.
Power-On Reset (POR)
The power-on reset output is an open-drain N-channel de-
vice, requiring a pull-up resistor to either the input voltage or
output voltage for proper voltage levels. The POR output has
a delay time that is programmable with a capacitor from the
SET pin to ground. The delay time can be programmed to be
as long as 1 second.
The SET pin is a current source output that charges a
capacitor that sets the delay time for the power-on reset
output. The current source is a 1
μ
A current source that
charges a capacitor up from 0V. When the capacitor reaches
1.25V, the output of the POR is allowed to go high.
Open-Drain Driver (DRV)
The drive (DRV) pin is an open-drain output capable of
sinking 150mA of current. This output is controlled by a logic
level input, the switch (SW) pin. The switch pin is an active
high input and cannot be left floating.
