TS61 Series
Voltage Detector
Directions for use
1. Please use this IC within the stated maximum ratings. Operation beyond these limits may cause degrading or
permanent damage to the device.
2. When a resistor is connected between the V
IN
pin and the input CMOS output configurations, oscillation may occur
as a result of voltage drops at R
IN
if load current (I
OUT
) exists. (refer to the Oscillation Description
3. When a resisted is connected between the V
IN
pin and the input with CMOS output configurations, irrespective of
N-ch output configurations, oscillation may occur as a result of through current at the time of voltage release even if
load current (I
OUT
) does not exist. (refer to the Oscillation Description
4. In order to stabilize the IC’s operations, please ensure that V
IN
pin’s input frequency’s rise and fall times are more
than several
μ
s/V.
5. Please use N-ch open drains configuration, when a resistor R
IN
is connected between the V
IN
pin and power source.
In such cases, please ensure that R
IN
is less than k
and that C is more than 0.1
μ
F.

Oscillation Description
OUTPUT CURRENT OSCILLATION WITH THE CMOS OUTPUT CONFIGURATION
When the voltage applied at IN rises, release operations commence and the detector’s output voltage increases. Load
current (I
OUT
) will flow at R
L
. Because a voltage drop (R
IN
x I
OUT
) is produced at the R
IN
resistor, located between the
input (IN) and the V
IN
pin, the load current will flow via the IC’s V
IN
pin. The voltage drop will also lead to a fall in the
voltage level at the V
IN
pin. When the V
IN
pin voltage level falls below the detec voltage level, detect operations will
commence. Following detect operations, load current flow will cease and since voltage drop at R
IN
will disappear, the
voltage level at the V
IN
pin will rise and release operations will begin over again. Oscillation may occur with this
“release-detect-release” repetition. Further, this condition will also appear via means of a similar mechanism during
detect operations.
