Power Distribution Controllers
These families of parts are hot swap power controllers. The
HIP1015 and ISL6115 are targeted for +12V control
applications whereas the HIP1016and ISL6116 are targeted
for +5V control applications. Each has a hard wired
undervoltage (UV) monitoring and reporting threshold level
~17% lower than the nominal +12V and +5V.
The HIP1015 and ISL6115 have an integrated charge pump
allowing control of up to +16V using an external N-channel
MOSFET. The HIP1016 and ISL6116 can also be used to
control much higher positive or negative voltages in a low
side controller configuration. Both IC families feature
programmable overcurrent (OC) detection, current
regulation (CR) with time delay to latch off and soft start.
The significant differentiation is in the functionality of the
PGOOD feature, how and when it reports an UV condition.
On both of the ISL devices the PGOOD function is always
enabled once the IC is biased, monitoring and reporting a
UV condition on the ISEN pin. The PGOOD feature on the
HIP devices is disabled during turn-on of the external
MOSFET until the GATE pin voltage has reached a
particular voltage. (See the spec table for detail) PGOOD is
defaulted to VDD during this disabled period.
Tape and Reel devices can be specified by the addition of a
‘-T’ suffix to the following part numbers.

FUNCTION
DESCRIPTION
Current Set
Connect to the low side of the current sense resistor through the current limiting set resistor. This
pin functions as the current limit programming pin.
Current Sense
Connect to the more positive end of sense resistor to measure the voltage drop across this resistor.
External FET Gate Drive
Pin
Chip Return
Connect to the gate of the external N-Channel MOSFET. A capacitor from this node to ground
sets the turn-on ramp. At turn-on this capacitor will be charged to VDD +5V (HIP1015,
ISL6115) and to VDD (HIP1016, ISL6116) by a 10µA current source.
Chip Supply
Current Limit Timing
Capacitor
Power Good Indicator
12V chip supply. This can be either connected directly to the +12V rail supplying the switched
load voltage or to a dedicated VSS +12V supply.
Connect a capacitor from this pin to ground. This capacitor determines the time delay between
an overcurrent event and chip output shutdown (current limit time-out). The duration of current
limit time-out (in seconds) = 93kx CTIM (Farads).
Indicates that the voltage on ISEN pin is within specification. PGOOD is driven by an open
drain N-Channel MOSFET and is pulled low when the output is not within specification. On the
ISL6115 and ISL6116, PGOOD function is enabled once IC is properly biased. On the
HIP1015 and HIP1016 the PGOOD function is disabled until the GATE voltage is within +/-
2.5V of VDD.
Power ON
PWRON is used to control and reset the chip. The chip is enabled when PWRON pin is driven
high or is open. After a current limit time out, the chip is reset by a low level signal applied to
this pin. This input has 20µA pull up capability.
