Package Information
For the latest package outline information and land patterns
(footprints), go to www.maximintegrated.com/packages.
Note that a “+”, “#”, or “-” in the package code indicates RoHS
status only. Package drawings may show a different suffix
character, but the drawing pertains to the package regardless
of RoHS status.
Chip Information
PROCESS: BCD
Power-Supply Bypass Capacitor (C3)
The power-supply bypass capacitor (see the Typical
Operating Circuit) lowers the output impedance of the
power supply, and reduces the impact of the MAX13325/
MAX13326 charge-pump switching transients. Bypass
VDD with C3, the same value as C2, and place it physi-
cally close to the VDD and PGND pins.
Load-Dump Protection
With minimal external components, the MAX13325/
MAX13326 can be protected against automotive load-
dump conditions. See the Typical Operating Circuit.
nMOSFET (Q1)
Q1 should be selected to withstand the full-voltage expo-
sure (BVDSS > 45V). The gate-source turn-on voltage
should be chosen to be less than VCPS to ensure initial
startup. Using an external nMOS, RTR020N05, 300ms
duration component provides 50V load-dump protection.
Zener Diode (D1)
During short-to-battery condition, OUT_ lifts up CHOLD
using an internal diode. In order not to violate the maxi-
mum gate-source voltage of Q1, a zener diode of appro-
priate clamping voltage should be added between the
gate and source terminals.
Series Resistor (R1)
Normally, a series resistor for current limitation is needed
during short-to-battery condition. R1 should be chosen
according to (18V - VDD(min) - VZENER)/1mA so that no
excessive current is being drawn from CHOLD.
Layout and Grounding
Proper layout and grounding are essential for optimum
performance. Connect the EP and GND together at a
single point on the PCB. Ensure ground return resistance
is minimized for optimum crosstalk performance.
