Pin 1 (Boost Drive):
Recharges and clamps the bootstrap
capacitor to 14.5V higher than pin 13 via an external diode.
Pin 2 (V
+
):
Main supply pin; must be closely decoupled to
the ground pin 7.
Pin 3 (Bias):
Decouple point for the internal 2.6V bias
generator. Pin 3 cannot have any external DC loading.
Pin 4 (Enable):
When left open, the LT1158 operates
normally. Pulling pin 4 low holds both MOSFETs off
regardless of the input state.
Pin 5 (Fault):
Open collector NPN output which turns on
when V12 – V11 exceeds the fault conduction threshold.
Pin 6 (Input):
Taking pin 6 high turns the top MOSFET on
and bottom MOSFET off; pin 6 low reverses these states.
An input latch captures each low state, ignoring an ensu-
ing high until pin 13 has gone below 2.6V.
Pin 8 (Bottom Gate Feedback):
Must connect directly to
the bottom power MOSFET gate. The top MOSFET turn-on
is inhibited until pin 8 has discharged to 1.5V. A hold-on
current source also feeds the bottom gate via pin 8.
Pin 9 (Bottom Gate Drive):
The high current drive point
for the bottom MOSFET. When a gate resistor is used, it is
inserted between pin 9 and the gate of the MOSFET.
PI FU
U
Pin 10 (V
+
):
Bottom side driver supply; must be con-
nected to the same supply as pin 2.
Pin 11 (Sense Negative):
The floating reference for the
current limit comparator. Connects to the low side of a
current shunt or Kelvin lead of a current-sensing MOSFET.
When pin 11 is within 1.2V of V
+
, current limit is inhibited.
Pin 12 (Sense Positive):
Connects to the high side of the
current shunt or sense lead of a current-sensing MOSFET.
A built-in offset between pins 11 and 12 in conjunction
with R
SENSE
sets the top MOSFET short-circuit current.
Pin 13 (Top Source):
Top side driver return; connects to
MOSFET source and low side of the bootstrap capacitor.
Pin 14 (Top Gate Feedback):
Must connect directly to the
top power MOSFET gate. The bottom MOSFET turn-on is
inhibited until V14 – V13 has discharged to 1.75V. An on-
chip charge pump also feeds the top gate via pin 14.
Pin 15 (Top Gate Drive):
The high current drive point for
the top MOSFET. When a gate resistor is used, it is inserted
between pin 15 and the gate of the MOSFET.
Pin 16 (Boost):
Top side driver supply; connects to the
high side of the bootstrap capacitor and to a diode either
from supply (V
+
< 10V) or from pin 1 (V
+
> 10V).
