LV5693P
Monolithic Linear IC
For Car Audio Systems
Multi-Power Supply System IC
Overview
LV5693P 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 5.7V, 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.

note) The control terminal is input 3.3V correspondence. Please set it by the input resistance at 5V input.
(Warning) Usage of CTRL2
When CTRL pin transits between L and M2, since it passes M1, ILM is turned on for a moment. Likewise, when CTRL
pin transits between H and M1, since it passes M2, ILM is turned off for a moment.
To avoid operation failure by the above factors, please refer to the following precautions.
• Do not connect parasitic capacitor to CTRL as much as possible.
• If use of capacitor for CTRL is required, keep the resistance value as low as possible.
• Make sure that the output load capacitor has enough marjin against the voltage fluctuation due to instantaneous
ON/OFF.
