AP1610
General Description
The AP1610 SmartSwitch is a current limited P-channel
MOSFET power switch designed for high-side load
switching applications. This switch operates with inputs
ranging from 2.4V to 5.5V, making it ideal for both 3V
and 5V systems. An integrated current-limiting circuit
protects the input supply against large currents which
may cause the supply to fall out of regulation. The
AP1610 is also protected from thermal overload which
limits power dissipation and junction temperatures. It can
be used to control loads that require up to 1A. Current
limit threshold is programmed with a resistor from SET
to ground. The quiescent supply current is typically a low
9µA. In shutdown mode, the supply current decreases to
less than 1µA.
The AP1610 is available in a Pb-free 5-pin SOT23 or
8-pin SC70JW package and is specified over the -40°C to
+85°C temperature range.

Application Information
Setting Current Limit
In most applications, the variation in ILIM must be taken into
account when determining RSET. The ILIM variation is due to
processing variations from part to part, as well as variations
in the voltages at IN and OUT, plus the operating
temperature. These three factors add up to a ±25% tolerance
Figure 1 illustrates a cold device with a statistically higher
current limit and a hot device with a statistically lower
current limit, both with RSET equal to 8.08kΩ. While the
chart, "RSET vs. ILIM" indicates an ILIM of 0.7A with an RSET
of 8.08kΩ, this figure shows that the actual current limit
will be at least 0.525A and no greater than 0.880A.
Figure 1: Current Limit Using 8.08kΩ.
To determine RSET, start with the maximum current drawn
by the load and multiply it by 1.33 (typical ILIM = minimum
ILIM / 0.75). This is the typical current limit value. Next,
refer to "RSET vs. ILIM" and find the RSET that corresponds to
the typical current limit value. Choose the largest resistor
available that is less than or equal to it. For greater precision,
the value of RSET may also be calculated using the ILIM RSET
product found in the chart "RSET Coefficient vs. ILIM." The
maximum current is derived by multiplying the typical
current for the chosen RSET in the chart by 1.25. A few
standard resistor values are listed in the table "Current Limit
RSET Values."

Example: A USB port requires 0.5A. 0.5A multiplied by
1.33 is 0.665A. From the chart named "RSET vs. ILIM," RSET
should be less than 9.15kΩ. 8.08kΩis a standard value that
is a little less than 9.15kΩ but very close. The chart reads
approximately 0.700A as a typical ILIM value for 8.08kΩ.
Multiplying 0.700A by 0.75 and 1.25 shows that the
AP1610 will limit the load current to greater than 0.525A
but less than 0.875A.
Operation in Current Limit
When a heavy load is applied to the output of the AP1610,
the load current is limited to the value of ILIM determined by
RSET. See Figure 2, "Overload Operation." Since the load is
demanding more current than ILIM, the voltage at the output
drops. This causes the AP1610 to dissipate a larger than
nor-mal quantity of power, and its die temperature to
increase. When the die temperature exceeds an
over-temperature limit, the AP1610 will shut down until is
has cooled sufficiently, at which point it will startup again.
The AP1610 will continue to cycle on and off until the load
is removed, power is removed, or until a logic high level is
applied to ON.
Enable Input
In many systems, power planes are controlled by integrated
circuits which run at lower voltages than the power plane
itself. The enable input ON of the AP1610 has low and high
threshold voltages that accommodate this condition. The
threshold voltages are compatible with 5V TTL and 2.5V to
5V CMOS.
Reverse Voltage
The AP1610 is designed to control current flowing from IN
to OUT. If a voltage is applied to OUT which is greater
than the voltage on IN, large currents may flow. This
could cause damage to the AP1610
