LTC7000
Fast High Voltage Protected
High Side NMOS Static Switch Driver
DESCRIPTION
The LTC7000 is a fast high voltage 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 LTC7000 operates over a 3.5V to 135V 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 LTC7000 can be configured to automatically retry or remain off until input is cycled.
The demo board includes input capacitors and output diode to accommodate input and output supply induc­tance 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 net work to control inrush current are also included.
The LTC7000 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 2537A. Proper board layout is essential for maximum thermal and electrical performance. See the data sheet sections for details. The LTC7000 is available in 16-lead MSOP package and three operating junction temperature grades (extended and industrial –40°C to 125°C, high temp automotive –40°C to 150°C and a mili­tary grade –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 switch­ing transitions, care must be taken to avoid a long ground lead on the oscilloscope probe. Measure the output volt­age 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 9V 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
on for 300µs time.
switch
9. Placing SW1 to OFF position, moving JP1 to INPUT position connects INPUT terminal to LTC7000 INP pin. An INPUT pin voltage of 2.2V or more will turn-on the high side switch.
