DESCRIPTION
LTC7003
Fast 60V Protected High Side
NMOS Static Switch Driver
Demonstration circuit 2749A is a 60V protected, high
side switch featuring the LT C
®
7003. The demo board is
designed to switch a 14.5A output load from input volt-
ages from 6V to 60V. The wide input range and low shut-
down current (1µA typical) make it suitable for automo-
tive, industrial, medical instrument and telecom applica-
tions. This board offers a low 45ns (typical) propagation
delay, fast switching times (<10ns) and 100% duty cycle
operation.
The LTC7003 is a fast protected high side N-channel
MOSFET driver. An internal charge pump fully enhances
an external N-channel MOSFET switch, allowing it to
remain on indefinitely. Its powerful gate driver can drive
large gate capacitance MOSFETs with very short transition
times, ideal for both high frequency switching and static
switch applications. The LTC7003 operates over a 3.5V to
60V input supply range. When an external current sense
resistor and internal comparator sense that the switch
current has exceeded a preset level, a fault flag is asserted
and the switch is turned off after a period of time set
by an external timing capacitor. After a cooldown period,
the LTC7003 can be configured to automatically retry or
remain off until the input is recycled. All registered trademarks and trademarks are the property of their respective owners.
PERFORMANCE SUMMARY
The demo board includes input capacitors and output
diode to accommodate input and output supply induc-
tance when switching loads. The switch can be controlled
directly with external signal or using the on-board on/off
switch. A single-shot pulse generator is included for evalu-
ating switching times while limiting output power. Optional
auxiliary VCC input accommodates gate power associated
with high frequency switching. Positions for RC delay net -
work to control inrush current are also included.
The LTC7003 data sheet gives a complete description of
the part, operation and application information. The data
sheet must be read in conjunction with this demo manual
for demo circuit 2749A. Proper board layout is essential
for maximum thermal and electrical performance. See the
data sheet sections for details. The LTC7003 is available
in 16-lead MSOP package and three operating junction
temperature grades extended and industrial from –40°C
to 125°C, high temp automotive from –40°C to 150°C and
a military grade from –55°C to 150°C.

QUICK START PROCEDURE
Refer to Figure 1 for proper measurement equipment
setup and follow the procedure below:
NOTE:When measuring the output voltage during switch-
ing transitions, care must be taken to avoid a long ground
lead on the oscilloscope probe. Measure the output volt-
age by touching the probe tip and ground ring directly
across the output capacitor as shown in Figure 2.
1. Place SW1 to OFF position. Move JP1 from the PULSE
(default position) to ON/OFF position (load on continu-
ously when SW1 is ON).
2. With input power supply set to zero volts and power
off, connect the input power supply to +VIN and GND.
3. With power off, connect load from +VOUT to GND.
4. Turn on the input power supply and increase the input
voltage slowly to 7V minimum. The input range is up
to 60V but hot-plugging with long leads may result in
input voltages in excess of 60V.
5. Place SW1 to ON position.
6. Check for the proper output voltage using a voltmeter.
Output voltage should be close to input voltage.
NOTE: If there is no output, temporarily disconnect the
load and cycle SW1 (the ON/OFF switch) or press reset
pushbutton SW2. If output is good, the load may be
set too high.
7. Once the proper output voltage is established, adjust
the load, if desired, to test current limit.
8. Placing SW1 to OFF position, moving JP1 to PULSE
position then placing SW1 in ON position will allow
pulse operation. Pushing SW2 will turn the high side
switch on for 300µs time.
9. Placing SW1 to OFF position, moving JP1 to INPUT
position connects INPUT terminal to LTC7003 INP pin.
An INPUT pin voltage of 2.2V or more will turn-on the
high side switch.
