Block Diagram
The CS5111 is a dual output power sup-
ply integrated circuit. It contains a 5V
±2%, 100mA linear regulator, a watchdog
timer, a linear output voltage monitor to
provide a Power On Reset (POR) and a
1.4A current mode PWM switching reg-
ulator.
The 5V linear regulator is comprised of
an error amplifier, reference, and super-
visory functions. It has low internal sup-
ply current consumption and provides
1.2V (typical) dropout voltage at maxi-
mum load current.
The watchdog timer circuitry monitors
an input signal (WDI) from the micro-
processor. It responds to the falling
edge of this watchdog signal. If a correct
watchdog signal is not received within
the externally programmable time, a
reset signal is issued.
The externally programmable active
reset circuit operates correctly for an out-
put voltage (V
LIN
) as low as 1V. During
power up, or if the output voltage shifts
below the regulation limit,
gles low and remains low for the duration
of the delay after proper output voltage
regulation is restored. Additionally a reset
pulse is issued if the correct watchdog is
not received within the programmed
time. Reset pulses continue until the cor-
rect watchdog signal is received. The
reset pulse width and frequency, as well
as the Power On Reset delay, are set by
one external RC network.
tog-
The current mode PWM switching regu-
lator is comprised of an error amplifier
with selectable feedback inputs, a cur-
rent sense amplifier, an adjustable oscil-
lator, and a 1.4A output power switch
with anti-saturation control. The switch-
ing regulator can be configured in a
variety of topologies.
The CS5111 is load dump capable and
has protection circuitry which includes
overvoltage shutdown, current limit on
the linear and switcher outputs, and an
overtemperature limiter.
