How to set USB overcurrent limit value (OCP)
OCP of the USB works when the voltage of RSNS is under VCC-0.3V. The peak current value of OCP is calculated as
follws: Ipeak(A) =0.3/R3. (ex.) R3=0.1
Ω → Ipeak=3A
Since this IC does not detect the heat generation of the external FET,
keep the temperature of the FET as low as possible so as not to exceed
the eatings.
Recommended FET: SANYO 2SJ650.
(note)The above values were obtained under typcal conditions. The
values may fluctuate in manufacturing processes due to external
resistor and IC variation.
Warning
The internal circuit of USBGT and RSNS consist of components that support 5V. Do not bias 7V or above between VCC
and these pins to prevent the IC from destruction. Do not use the device under overvoltaged condition(for example
shorting these terminals to low voltage node) even for short period of time .
In normal operating condition with recommended application, the device controls voltage of these terminals within 5V.
Caution for implementing LV5693P to a system board
The package of LV5693P is HZIP15J which has some metal exposures other than connection pins and heatsink as shown in the
diagram below. The electrical potentials of (2) and (3) are the same as those of pin 15 and pin 1, respectively. (2) (=pin 15) is the VCC
pin and (3) (=pin 1) is the ILM (regulator) output pin. When you implement the IC to the set board, make sure that the bolts and the
heatsink are out of touch from (2) and (3). If the metal exposures touch the bolts which has the same electrical potential with GND,
GND short occurs in ILM output and VCC. The exposures of (1) are connected to heatsink which has the same electrical potential with
substrate of the IC chip (GND). Therefore, (1) and GND electrical potential of the set board can connect each other.
