LV5692P
Monolithic Linear IC
For Car Audio Systems
Multi-Power Supply System IC
Overview
LV5692P is a multiple voltage regulator for car audio system, which allows reduction of quiescent current. This IC has 5
systems of voltage regulator pre-driver for P-FET which generates USB power and a high side switch for external devices.
The following protection circuits are integrated: over current protector, overvoltage protector and Thermal Shut Down.
This IC is suitable for use in car audio with USB port.
Features
• Five channel regulator and one channel P-FET pre-driver (for USB-power)
For VDD: VOUT is 3.3V, IOmax is 300mA
For DSP: VOUT is 3.3V, IOmax is 300mA
For CD: VOUT is 8.0V, IOmax is 1300mA
For illumination: VOUT is 8.4V, IOmax is 500mA
For audio systems: VOUT is 8.4V, IOmax is 500mA
For USB (controller), VOUT is flexible (configurable with external resistor), IOmax is 1000mA
• High side switch: Voltage difference between input and output is 0.5V, IOmax is 500mA
• Over current protector
• Overvoltage protector (Without VDD-OUT) Clamp voltage is 21V (typical)
• Thermal Shut down 175ºC (typical)
• Quiescent current 50μA (Typ. when only VDD is in operation)
(Warning) The protector functions only improve the IC’s tolerance and they do not guarantee the safety of the IC if used under the
conditions out of safety range or ratings. Use of the IC such as use under over current protection range or thermal shutdown state may
degrade the IC’s reliability and eventually damage the IC.

LV5692P
• 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=0.1Ω → 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.
Outout current Ipeak
• 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.
Caution for implementing LV5692P to a system board
The package of LV5692P 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.
