Pin Description

Pin Name
Pin Function
1
FLG
Fault Flag: (Output): Open-collector output sinks current upon overcurrent,
open-load, or overtemperature detection. 10mA maximum load.
2
DLY
Overcurrent Delay Time Capacitor: Optional. Capacitor to ground delays
activation of overcurrent shutdown.
3
CTL
Control (Input): TTL compatible on/off control input. Logic high drives the
gate output above the supply voltage. Logic low forces the gate output near
ground. Logic low also resets the overcurrent fault latch.
4
EN
Enable (Input): CMOS compatible input. Logic high enables the charge
pump. Logic low disables the charge pump and draws near zero supply
current.
5
GND
Ground: Power return.
6
CS
Internal Supply Storage Capacitor: 10
μ
F external capacitor to GND.
Provides additional current to internal circuitry during switching transitions.
7
VDD
Supply (Input): +4.5V to +30V supply.

CP1–
Charge Pump Capacitor #1: Refer to CP1+.
9
CP2–
Charge Pump Capacitor #2: Refer to CP2+.
10
CP1+
Charge Pump Capacitor #1: External 0.01
μ
F voltage tripler capacitor.
11
CP2+
Charge Pump Capacitor #2: External 0.01
μ
F voltage tripler capacitor.
12
CB
Bootstrap Capacitor: 0.1
μ
F capacitor to source for fastest rise time.
13
S
Source: Source connection to external MOSFET.
14
RV
Reference Voltage Resistor: Resistor to VDD provides a reference voltage
drop. A voltage drop across the external MOSFET that is greater than the
voltage drop across the reference resistor indicates an overcurrent condition.
(Refer to applications section) Zero temperature coefficient resistor
recommended.
15
RI
Reference Current Resistor: Resistor to GND sets constant current value
through RV resistor (Refer to applications section) and matches tempera-
ture compensation of RV resistor. Zero temperature coefficient resistor
recommended.
16
G
Gate (Output) : Gate connection to external MOSFET.
