Application Details
PNP Transistor (DDTB122LU) and ESD Protected
N-MOSFET (DMN601TK) integrated as one in
LMN400E01 can be used as a discrete entity for
general application or as an integrated circuit to
function as a Load Switch. When it is used as the
latter as shown in Fig. 20, various input voltage
sources can be used as long as it does not exceed
the maximum ratings of the device. These devices
are designed to deliver continuous output load
current up to a maximum of 400 mA. The MOSFET
Switch draws no current, hence loading of control
circuitry is prevented. Care must be taken for higher
levels of dissipation while designing for higher load
conditions. These devices provide high power and
also consume less space. The product mainly helps
in optimizing power usage, thereby conserving
battery life in a controlled load system like portable
battery powered applications. (Please see Fig. 21
for one example of a typical application circuit used
in conjunction with a voltage regulator as a part of
power management system).
