Multi Voltage Regulator IC

Application Note

Overview

LV5692P/93P 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 Pch- FET which generates USB power

and a high side switch for external devices.

The following protection circuits are integrated: overcurrent protector, overvoltage protector and Thermal

Shut Down. This IC is suitable for use in car audio with USB port. The package is HZIP15J

Functions

 Quiescent Current 50uA ( Typ, when only VDD is in operation)

 5 channel regulators and 1channel P-FET pre-driver (for USB-POWER)

・ For VDD: Vout is 3.3V(LV5692P),5.7V(LV5693P), Iomax is 300mA

・ For DSP: Vout is 3.3V, Iomax is 300mA

・ For CD: Vout is 8.0V, Iomax is 1300mA

・ For Ilumi: Vout is 8.4V, Iomax is 500mA

・ For Audio: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

 Overcurrent protector

 Overvoltage protector (Without VDD-OUT) *Detection voltage is 21V (typical)

 Thermal Shut Down *175ºC (typical)

(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, LV5693P Application Note (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.

LV5692P, LV5693P Application Note Functional Description The LV5693P is a multiple output voltage regulator with a power switch, suitable for use in car audio system. [Standby mode] When all CTRL pins are "L" state (CTRL1=CTRL2=CTRL3=L), LV5692P/93P is in standby mode. In standby mode, all outputs except VDD are disabled. Quiescent current is 50uA(typ) at VDD no load. When either CTRL pin exceeds "M1" threshold voltage, LV5693P exits standby mode.
PAGE 28
LV5692P, LV5693P Application Note [CTRL1/2/3 input] CTRL1 accepts three input values (L/M/H)., CTRL2 accepts four input values(L/M1/M2/H) and CTRL3 accepts two values(L/H). CTRL1/2/3 have a pull-down resistance, and this resistance value is 400kΩ. Logic table is shown on page7. [VCC/VCC1] VCC1 voltage must be higher than VCC-0.7V, because internal diode between VCC and VCC1 becomes positively biased.
PAGE 29
LV5692P, LV5693P Application Note In using LV5692P/93P, you have to check the following prior to the set design. 1. Absolute Maximum Rating (Common notes to general semiconductor device) Stresses exceeding Maximum Ratings may damage the device. If stresses exceeding Maximum Ratings are applied to an IC, it might smoke or fire by the breakdown and the overheating. We recommend derating design for reducing failure rate of device. A guide of general derating design is described below.

LV5692P, LV5693P Application Note 5. Over -Current Protection Each channel has an Over-Current Protection (OCP) circuit which is the "Fold-Back" type, OCP circuit prevent IC’s break down at an over current condition. This circuit is useful against sudden over current, but use of continuous operation is not allowed. The limit value of output current is changed by ambient temperature and production tolerance.

LV5692P, LV5693P Application Note 8. Notes on Installation Package "HZIP15J", there are some places where metal is exposed except terminals and a heat sink. This includes the one connecting with the function pin. Especially, when you mount hardware covers over the IC, do not bring “②” & ”③” (in below figure) into contact with mounting hardware. The potential of point “①” as well as the heat sink is equal to GND.
PAGE 32
LV5692P, LV5693P Application Note HZIP15J Heat sink attachment Heat sinks are used to lower the semiconductor device junction temperature by leading the head generated by the device to the outer environment and dissipating that heat. ａ．Unless otherwise specified, for power ICs with tabs and power ICs with attached heat sinks, solder must not be applied to the heat sink or tabs. ｂ．Heat sink attachment ・Use flat-head screws to attach heat sinks.
