MAX17613C
4.5V to 60V, 3A Current-Limiter with
OV, UV and Reverse Protection
General Description
The Olympus series of ICs is the industry's smallest and
most robust integrated system protection solution. The
MAX17613A/MAX17613B/MAX17613C adjustable over-
voltage and overcurrent protection devices are ideal to
protect systems against positive and negative input volt-
age faults up to +60V and -65V, and feature low 130mΩ
(typ) RON FETs.
The adjustable input overvoltage protection range is 5.5V
to 60V and the adjustable input undervoltage protec-
tion range is 4.5V to 59V. The input overvoltage-lockout
(OVLO) and undervoltage-lockout (UVLO) thresholds are
set using external resistors. Additionally, the devices offer
an internal input undervoltage threshold at 4.2V (typ).
The devices feature programmable current-limit protection
up to 3A; hence, controlling the inrush current at startup
while charging high capacitance at the output. The current-
limit threshold is programmed by connecting a resistor from
the SETI pin to GND. When the device current reaches
the programmed threshold, the device prevents further
increases in current by modulating the FET resistance. The
devices can be programmed to behave in three different
ways under current-limit condition: autoretry, continuous,
or latchoff modes. The voltage appearing on the SETI pin
is proportional to the instantaneous current flowing through
the device and can be read by an ADC.
MAX17613A and MAX17613C block current flowing
in the reverse direction (i.e., from OUT to IN) whereas
MAX17613B allows current flow in the reverse direction.
The devices feature thermal shutdown protection against
excessive power dissipation.
The devices are available in a small, 20-pin (4mm x 4mm)
TQFN-EP package and operate over the -40°C to +125°C
extended temperature range.
Ordering Information appears at end of data sheet.
