○Cautions on use

(1) Absolute Maximum Ratings

An excess in the absolute maximum ratings, such as supply voltage, temperature range of operating conditions, etc.,

can break down devices, thus making impossible to identify breaking mode such as a short circuit or an open circuit. If

any special mode exceeding the absolute maximum ratings is assumed, consideration should be given to take physical

safety measures including the use of fuses, etc.

(2) Power supply and GND line

Design PCB pattern to provide low impedance for the wiring between the power supply and the GND lines. Pay

attention to the interference by common impedance of layout pattern when there are plural power supplies and

GND lines. Especially, when there are GND pattern for small signal and GND pattern for large current included the

external circuits, please separate each GND pattern. Furthermore, for all power supply terminals to ICs, mount a

capacitor between the power supply and the GND terminal. At the same time, in order to use a capacitor, thoroughly

check to be sure the characteristics of the capacitor to be used present no problem including the occurrence of capacity

dropout at a low temperature, thus determining the constant.

(3) GND voltage

Make setting of the potential of the GND terminal so that it will be maintained at the minimum in any operating state.

Furthermore, check to be sure no terminals are at a potential lower than the GND voltage including an actual electric

transient.

(4) Short circuit between terminals and erroneous mounting

In order to mount ICs on a set PCB, pay thorough attention to the direction and offset of the ICs. Erroneous mounting

can break down the ICs. Furthermore, if a short circuit occurs due to foreign matters entering between terminals or

between the terminal and the power supply or the GND terminal, the ICs can break down.

(5) Operation in strong electromagnetic field

Be noted that using ICs in the strong electromagnetic field can malfunction them.

(6) Input terminals

In terms of the construction of IC, parasitic elements are inevitably formed in relation to potential. The operation of the

parasitic element can cause interference with circuit operation, thus resulting in a malfunction and then breakdown of

the input terminal. Therefore, pay thorough attention not to handle the input terminals, such as to apply to the input

terminals a voltage lower than the GND respectively, so that any parasitic element will operate. Furthermore, do not

apply a voltage to the input terminals when no power supply voltage is applied to the IC. In addition, even if the power

supply voltage is applied, apply to the input terminals a voltage lower than the power supply voltage or within the

guaranteed value of electrical characteristics.

(7) External capacitor

In order to use a ceramic capacitor as the external capacitor, determine the constant with consideration given to a

degradation in the nominal capacitance due to DC bias and changes in the capacitance due to temperature, etc.

(8) Thermal shutdown circuit (TSD)

This LSI builds in a thermal shutdown (TSD) circuit. When junction temperatures become detection temperature or

higher, the thermal shutdown circuit operates and turns a switch OFF. The thermal shutdown circuit, which is

aimed at isolating the LSI from thermal runaway as much as possible, is not aimed at the protection or guarantee

of the LSI. Therefore, do not continuously use the LSI with this circuit operating or use the LSI assuming its

operation.

(9) Thermal design

Perform thermal design in which there are adequate margins by taking into account the permissible dissipation

(Pd) in actual states of use.

(10) LDO

Use each output of LDO by the independence. Don’t use under the condition that each output is short-circuited

because it has the possibility that a operation becomes unstable.

(11) DC/DC converter

Please select the low DCR inductors to decrease power loss for DC/DC converter.

(12) Other cautions on use

Please consult supplementary documents such as function description of this LSI.
