Technical Note
● Peripheral Settings for Pins and Precautions
1) V CC pins
Insert capacitors with a capacitance of 0.33 μ F to 1000 μ F between the V CC and GND pins.
The capacitance varies with the application. Be sure to design the capacitance with a sufficient margin.
2) Capacitors for stopping oscillation for output pins
Capacitors for stopping oscillation must be placed between each output pin and the GND pin. Use a capacitor within a
capacitance range between 0.1 μ F and 1000 μ F. Since oscillation does not occur even for ESR values from 0.001 Ω to
100 Ω , a ceramic capacitor can be used. Abrupt input voltage and load fluctuations can affect output voltages. Output
capacitor capacitance values should be determined after sufficient testing of the actual application.
● Operation Notes
1) Absolute maximum ratings
Use of the IC in excess of absolute maximum ratings such as the applied voltage or operating temperature range may
result in IC damage. Assumptions should not be made regarding the state of the IC (short mode or open mode) when
such damage is suffered. A physical safety measure such as a fuse should be implemented when use of the IC in a
special mode where the absolute maximum ratings may be exceeded is anticipated.
2) GND potential
Ensure a minimum GND pin potential in all operating conditions.
3) Setting of heat
Use a thermal design that allows for a sufficient margin in light of the power dissipation (Pd) in actual operating conditions.
4) Pin short and mistake fitting
Use caution when orienting and positioning the IC for mounting on printed circuit boards. Improper mounting may result in
damage to the IC. Shorts between output pins or between output pins and the power supply and GND pins caused by the
presence of a foreign object may result in damage to the IC.
5) Actions in strong magnetic field
Use caution when using the IC in the presence of a strong magnetic field as doing so may cause the IC to malfunction.
6) Testing on application boards
When testing the IC on an application board, connecting a capacitor to a pin with low impedance subjects the IC to stress.
Always discharge capacitors after each process or step. Be sure to turn power off when mounting or dismounting jigs at
the inspection stage. Furthermore, for countermeasures against static electricity, ground the equipment at the assembling
stage and pay utmost attention at the time of transportation or storing the product.
7) This monolithic IC contains P+ isolation and P substrate layers between adjacent elements in order to keep them isolated.
PN junction is formed by the P layer and the N layer of each element, and a variety of parasitic elements will be
constituted.
For example, when a resistor and transistor are connected to pins as shown in Fig. 19,
? the P/N junction functions as a parasitic diode when GND>Pin A for the resistor or GND>Pin B for the transistor
(NPN).
? Similarly, when GND ＞ Pin B for the transistor (NPN), the parasitic diode described above combines with the N
layer of other adjacent elements to operate as a parasitic NPN transistor.
