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 VIN pin and the input CMOS output configurations, oscillation may occur
as a result of voltage drops at RIN if load current (IOUT) exists. (refer to the Oscillation Description ① below).
3. When a resisted is connected between the VIN 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 (IOUT) does not exist. (refer to the Oscillation Description ② below)
4. In order to stabilize the IC’s operations, please ensure that VIN pin’s input frequency’s rise and fall times are more
than several µs/V.
5. Please use N-ch open drains configuration, when a resistor RIN is connected between the VIN pin and power source.
In such cases, please ensure that RIN is less than kΩ and that C is more than 0.1µF.

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 (IOUT) will flow at RL. Because a voltage drop (RIN x IOUT) is produced at the RIN resistor, located between the
input (IN) and the VIN pin, the load current will flow via the IC’s VIN pin. The voltage drop will also lead to a fall in the
voltage level at the VIN pin. When the VIN 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 RIN will disappear, the
voltage level at the VIN 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.

Oscillation Description (Continue)
OUTPUT CURRENT OSCILLATION WITH THE CMOS OUTPUT CONFIGURATION
Since the TS61 series are CMOS ICs, through current will flow when the IC’s internal circuit switching operates (during
release and detect operations). Consequently, oscillation is liable to occur as a result of drops in voltage at the through
current’s resistor (RIN) during release voltage operations (refer to diagram 2). Since hysteresis exists during detect
operation, oscillation is unlikely to occur.
Diagram 2: Oscillation in relation to through current
Function Description
1. When input voltage (VIN) rises above detect voltage (VDF), output voltage (VOUT) will be equal to VIN. (A condition of
high impedance exists with N-ch open drain output configurations).
2. When input voltage (VIN) falls below detect voltage (VDF), output voltage will be equal to the ground voltage (VSS).
3. When input voltage (VIN) falls to a level below that of the minimum operating voltage (VMIN), output will become
unstable. In this condition, VIN will equal the pulled-up output (should output be pull-up).
4. When input voltage (VIN) rises above the ground voltage (VSS) level, output will be unstable at levels below the
minimum operating voltage (VMIN). Between the VMIN and detect release voltage VDR level, the ground voltage (VSS)
level will be maintained.
5. When input voltage (VIN) rises above detect release voltage (VDR), output voltage (VOUT) will be equal to VIN. (A
condition of high impedance exists with N-ch open drain output configurations.)
6. The difference between VDR and VDF represents the hysteresis range.
