There tests were performed with pulse load to minimize the increase of junction temperature (Tj). *3：The VDD5V output supplies the output currents of SW5V and ACC5V. Therefore, the current supply capability of the VDD5V output and its other electrical characteristics are affected by the output statuses of SW5V and ACC5V. *4：SW5V and ACC5V outputs have no load. *5：When a resistor tolerance ±1% is used. <Reference> When a resistor tolerance ±0.5% is used, Vo3’ ’ is 8.67V≦9.0V≦9.33V. *6：When a resistor tolerance ±1% is used. The absolute accuracy of the internal resistance is ±15%. *7：Since the "SW5V" and "ACC5V" are output from "VDD5V" through the switch, each output voltage drops by an amount equivalent to the ON resistance of the switch. http://onsemi.com 7 LV56801P Application Note True Table of CTRL CTRL1 ANT EXT ILM CTRL2 CD AUDIO SW5 L OFF OFF OFF L OFF OFF OFF M1 OFF OFF ON M OFF ON ON M2 OFF ON ON H ON ON ON H ON ON ON Timing Chart 21V VCC (7PIN) VDD3.3V OUT (12PIN) CTRL1 (8PIN) CTRL2 (6PIN) CD OUT (3PIN) AUDIO OUT (5PIN) ILM OUT I (1PIN) L EXT OUT M (15PIN) ANT OUT (14PIN) SW5V OUT (13PIN) ACC IN (10PIN) 3.0V 2.7V ACC OUT (11PIN) Fig6.

VCC This IC has the tolerance value of 50V against VCC peak surge voltage, but for more safety set design, adding power clamp, such as power zenner diode, on battery connected line is recommended in order to absorb applied surge. This IC has no protection against battery reverse connection, so adding Schottky diode is recommended to prevent a negative voltage. Linear Regulators All regulators in LV5680P are low dropout outputs, because the output stage of all regulators is PLDMOS. When you select output capacitors for linear regulators, you should consider three main characteristics: startup delay, transient response and loop stability. The capacitor values and type should be based on cost, availability, size and temperature constraints. Tantalum, Aluminum electrolytic, Film, or Ceramic capacitors are all acceptable solutions. However, attention must be paid to ESR constraints. The aluminum electrolytic capacitor is the least expensive solution, but if the circuit operates at low temperatures(-25 to -40 ℃ ), both the value and ESR of the capacitor will vary considerably. The capacitor manufacturer's datasheet usually provides this information. VDD3.3V regulator (3.3V, 0.2A) When VCC is applied, VDD3.3V output is active regardless of CTRL states. VDD3.3V output supplies the current to SW3.3V and ACC3.3V output. Therefore, the current supply capability of VDD3.3V output and its other electrical characteristics are affected by the condition of SW5V and ACC5V output. The over-current limiting circuit of VDD3.3V, SW3.3V, and ACC3.3V is common. So when the total output current value of three terminals reaches the limit value, the over-current limiting circuit operates. CD regulator (8.0V, 1.3A) When CTRL2 is “H”, CD output is active. CD output has the highest current capability of four regulators in LV5680P. AUDIO regulator (8-9V, 0.3A) When CTRL2 is “M” & “H”, AUDIO output is active. AUDIO output should set the output voltage by external resistance. For the setting method of the voltage, please refer to the explanation of this application note p.22. ILM regulator (8-12V, 0.3A) When CTRL1 is “M1”, “M2” & “H”, ILM output is active. ILM output voltage can be adjusted by external resistance between ILM and ILM_F. If there is no external resistance, ILM output voltage is 12V by built-in resistance. For the setting method of the voltage, please refer to the explanation of this application note p.22. EXT & ANT high-side switches The two high-side power switches connected to VCC are a 350mA output (EXT) and a 300mA output (ANT). If these outputs are connected to inductive load or loads which have different ground potential, diodes (D2 and D4 in Fig.4) are necessary to protect the device from negative voltage. SW3.3V switch This high-side switch connected to VDD3.3V is a 200mA output. When CTRL2 is “M” & “H”, SW3.3V output is active. A pull-down resistance (50kΩ) is connected between SW5V and GND. ACC detector circuit When ACC input voltage is over 3V (typ), ACC3.3V output is active. ACC3.3V output is a high-side switch connected to VDD3.3V. A pull-down resistance (50kΩ) is connected between ACC3.3V and GND. The ACC detection voltage has hysteresis http://onsemi.com 24 LV56801P Application Note characteristics, and the hysteresis value is 0.3V (typ). The ACC input has a pull-down resistance, and this resistance value is 60kΩ. ACC terminal is high-voltage input as well as VCC terminal. CTRL1, 2 input CTRL1 accepts four input values (L/M1/M2/H), and CTRL2 accepts three input values (L/M/H). CTRL1 & CTRL2 have a pull-down resistance, and this resistance value is 500kΩ. Logic table is shown at p.19. Protection Thermal Shutdown To protect the device from overheating a thermal shutdown circuit is included. If the junction temperature reaches approximately 175 ℃ (typ), all outputs are turned off regardless of CTRL state. Outputs remain disabled until the junction temperature drops below 145℃(typ)(automatic restoration). The thermal shutdown circuit does not guarantee the protection of the final product because it operates out of maximum rating (exceeding Tjmax=150℃). Current Limiting When the each output becomes in over load condition, the device limits the output current. All outputs are also protected against short circuit by fold back current limiter. Overvoltage The device is protected against load dump. When VCC voltage exceeds 21V, the device detects over voltage condition and turns all the outputs off except VDD to protect the device. If VCC voltage gets below 21V, outputs are automatically restored. . TEST Procedure Line regulation Line regulation is defined as the maximum change in output voltage as the input voltage is varied through the specified range. It is measured by changing the input voltage and measuring the minimum/maximum voltage of the output. Line regulation is defined as the difference between maximum and minimum voltage. Load regulation Load regulation is defined as the maximum change in output voltage as the load current is varied through the specified range. It is measured by changing the load current and measuring the minimum/maximum voltage of the output. Load regulation is defined as the difference between maximum and minimum voltage. Dropout voltage Dropout voltage is defined as the minimum input-to-output differential voltage at the specified load current required by the regulator to keep the output voltage in regulation. It is measured by reducing input voltage until the output voltage drops below the nominal value. Ripple rejection Ripple rejection is defined as the ratio of input ripple amplitude versus that of output. http://onsemi.com 25 LV56801P Application Note LV56801P is used, before the set design, must check the following 1. Absolute Maximum Rating (Common notes to general semiconductor device) Stresses exceeding Maximum Ratings may damage the device. If a IC is applied stresses exceeding Maximum Ratings, a IC might smoke or fire by the breakdown and the overheating. We recommend to derating design for reducing failure rate of device. A guide of general derating design is described below. (1)Stress Voltage: 80% or less for Abs Max voltage. (2)Maximum rating current: 80% or less for Abs Max Io. (3)Temperature: 80% or less for Temperatures rating. 2. Recommended Operating Range When LV5680P was used within Recommended Operating Range and Temperature Rating, unless otherwise specified, we do not guarantee the specified value in all temperature ranges. As long as the IC is at operation temperature range, IC’s characteristic doesn’t change suddenly. Operating conditions of the input voltage and the output current are limited by the chip maximum junction temperature (Tjmax). Please decide the value of the input voltage and the output current so as not to exceed Tjmax. 3. Output Capacitor Between GND and each output, please be sure to put capacitor to prevent oscillation. Because abrupt changes of input voltage and output load interfere in the output voltage, make sure to use the system that will actually be offered to the market and define the output capacitor after a sufficient evaluation. When selecting the capacitor, to ensure the required minimum capacity over all operating conditions of the application, it is necessary to consider the influence of a temperature and a applied voltage on the capacity value. Please design the PCB pattern that the output terminal and the capacitor are located as close as possible. 4. Parasitic Devices Output Power MOS-FET driver has, in device structure, parasitic diode like the figure below. Because in normal operating the input voltage is higher than the output voltage, the parasitic diode is reverse bias. If the output is higher than the input at abnormal operating, a current flows from the output to the input, because the parasitic diode is forward biased.

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. However, the limiting value doesn't fall below the output maximum current defined by the specification. When the output current uses it exceeding the maximum current, the OCP circuit might operate in some situations. Please design the equipment, to be sure than a specified value. Please design the output current to use without fail below a specified maximum value. Output current Spec limit (Iomax) Changes in temperature, etc Without OCP Limit Current Limit Current Iout Vout Output current operating range Vreg Iout≒ Iout Rload Rload OCP working area 6. Over-Voltage Protection When VCC voltage exceeds 21V, the device detects over voltage condition and shuts down all output but “VDD” to protect the device. The peak voltage value (Vcc peak) changes depending on Surge-waveform condition. Adding power clamp, such as power zenner diode, on battery connected line is recommended in order to absorb applied surge. 7. Thermal shut-down This IC built-in thermal shut-down circuit to prevent from thermal damage. If the state to exceed the Absolute Maximum Rating of the power dissipation continues, and the chip temperature (Junction temperature:Tj) reaches 175℃, the thermal shut-down circuit operates. When the thermal shut-down circuit operates, all outputs are turned off regardless of CTRL state. Outputs remain disabled until the junction temperature drops below 145℃(typ)(automatic restoration). If the operating condition is not changing, the output repeats on and off. The output seems to oscillate. * 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. 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 the mounting hardware covers 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. http://onsemi.com 27 LV56801P Application Note ・HZIP15J ① Connected Heat-sink Connected ② 15pin Connected ③ 1pin ① Connected Heat-sink Heat-sink Connected ① Heat-sink Heat-sink ：Expose metal part ※Same as other side ：Expose metal part ＜HZIP15J Top view＞ ＜HZIP15J Side view＞ *Caution :Do not bring “②” & ”③” into contact with mounting hardware. ① Connected Heat-sink ③ Connected 1pin ② Connected 15pin ① Connected Heat-sink ① Connected Heat-sink 9.
