Description
LTC7000-1
Fast High Voltage Protected
High Side NMOS Static Switch Driver
Demonstration circuit 2492A is a 135V protected, high
side switch featuring the LT C
®
7000-1. The demo board is
designed to switch a 5.5A output load from input voltages
from 8V to 135V. The wide input range and low shutdown
current (1µA typical) make it suitable for automotive,
industrial, medical instrument and telecom applications.
This board offers a low 50ns (typical) propagation delay,
fast switching times (<10ns) and 100% duty cycleopera-
tion.
The LTC7000-1 is a fast high voltage protected high side
N-channel MOSFET driver with high voltage pin spacing
(0.657mm). An internal charge pump fully enhances an
external N-channel MOSFET switch, allowing it to remain
on indefinitely. A 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 LTC7000-1 operates over a 3.5V to 135V
input supply range. When an external current sense resis-
tor 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
LTC7000-1 can be configured to automatically retry or
remain off until the input is re-cycled.

performance summary
The demo board includes input capacitors and an 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
evaluating switching times while limiting output power.
Optional auxiliary VCC input accommodates gate power
associated with high frequency switching. Positions for RC
delay network to control inrush current are alsoincluded.
The LTC7000-1 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 2492A. Proper board layout is essential
for maximum thermal and electrical performance. See the
data sheet sections for details. The LTC7000-1 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 version 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 volt 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 8V minimum. The input range is up
to 135V but hot-plugging with long leads may result
in input voltages in excess of 135V.
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 LTC7000-1 INP
pin. An INPUT pin voltage of 2.2V or more will turn-on
the high side switch.
