PIN CONFIGURATION
PIN DESCRIPTION
Pin Number
Function
Description
1
BOOST
Output of on-chip Boost converter. A 100-nF capacitor should be connected between BOOST and GND
2
V
DD
GATE
Positive supply pin.
3
Connection to external power MOSFET gate.
4
LOAD
Connection to positive supply side of LOAD.
5
SENSE
Connects external sense resistor of a sensefet sense pin to SENSE input of overcurrent trip comparator.
A standard MOSFET may also be used in conjunction with a low ohmic value shunt resistor.
6
LIMSET
Connects overcurrent limit set resistor R
LIMSET
to the reference input of overcurrent trip comparator.
CMOS logic input to control the overcurrent trip comparator sensitivity at power-on. HI/LO should be
connected to GND for low Capacitive loads and to V
DD
for high capacitive loads.
CMOS logic input to turn IC on or off. GATE voltage remains low when ENABLE is high.
7
HI/LO
8
ENABLE
9
R
BIAS
A resistor connected from this pin to GND programs the reference bias current for the overcurrent trip
comparator resistor R
LIMSET
and the GATE
(on)
charge current. See Functional Description for equations.
Input to voltage monitor comparator.
10
V
RST
11
STATUS
Open drain NMOS output. This pin is driven low when the current limiter is enabled and the LOAD
voltage is greater than 90% of V
DD
.
Open drain NMOS output. This pin is driven low during power on reset or when V
RST
is lower than the
internal 1.25-V reference.
12
RESET
13
C
RETRY
C
RST
GND
A capacitor connected from this pin to GND programs the retry timer.
14
A capacitor connected from this pin to GND programs the reset timer.
15
Negative supply pin.
16
COIL
Connection to Boost converter inductor.
