Can the LMD18200 and LMD18201 be paralleled to boost the output current?
The LMD18200 and LMD18201 can be paralleled, following these guidelines. If you follow (5) through (9) below, the devices will be very close together (physically). The need to keep the devices very close together limits the number that can be paralleled in any practical manner. • Except for the BOOTSTRAP 1 pins and BOOTSTRAP 2 pins, connect all pins of the same type together For example, if you”re paralleling 2 devices, drive both PWM inputs with the same signal, drive both DIRECTION inputs with the same signal, connect both OUTPUT 1 pins together and so forth. • For each device, connect a bootstrap capacitor between BOOTSTRAP 1 and the paralleled OUTPUT 1 pins. 2 devices require 2 capacitors. 3 means 3, and so forth. • For each device, connect a bootstrap capacitor between BOOTSTRAP 2 and the paralleled OUTPUT 2 pins. 2 devices require 2 capacitors. 3 means 3, and so forth. • Bypass each device as described in the data sheet. Do not skimp on bypassing. Doing so may destroy the device
