SGM2523
Programmable Current Limit Switch
SYSTEM EXAMPLES (continued)
range is from 2.6V to 22V. Programmable current limits,
programmable soft-start, over-temperature protection, fault
flag and under-voltage lockout are provided in the
SGM2523.
Smart Load Switch
The smart load switch is a series of MOSFETs used to
switch the load (resistance or inductance). It also
provides protection in case of failure. Figure 11 shows a
typical discrete implementation of load switch, which
requires more components and more complex circuits
to achieve fault protection. The SGM2523 can be used
as a load switch for the applications whose operating
Used as a load switch, Figure 11 shows a typical
implementation of SGM2523, which is used for driving
a solenoid and fan control. Freewheeling diode is
recommended for the highly inductive load.
