Power dissipation
When it is used in the ambient temperature of (Ta)=25°C and more, make reference to each thermal derating
characteristics of used package. Both Fig.5 and Fig.6 show these characteristic when ROHM's standard board
(70mmX70mmX1.6mm, glass epoxy board) is mounted.
Power consumption of the IC
SSOP5
(SMP5C2) package

(EMP5) package
Fig.5 Thermal derating curve
Fig.6 Thermal derating curve
Circuit current at ON/OFF is very small. Power consumption in output depends on each load connected with
V
OUT
pin. Please note that total power consumption must be within a power dissipation range in the secure area
of the entire operating temperature. Power dissipation of these packages; SSOP5
(SMP5C2)
package (BD52XXG/
BD53XXG) Fig.5, and VSOF5
(EMP5)
package (BD52XXFVE/BD53XXFVE) Fig.6 is shown below.
Electrical characteristics (
Unless otherwise noted; Ta=-25°C to 85°C)
1 Detection voltage (V
DET
) : V
DD
voltage when the output (Vout) goes from “H” to “L” .
2 Release voltage (V
DET
+ V
DET
) : V
DD
voltage when output (Vout) goes from “L” to “H” .
3 Hysteresis voltage ( V
DET
) : The difference between detection voltage and release voltage. Malfunction
due to noise in V
DD
(within hysteresis voltage) could be avoided by hysteresis
voltage.
