Description
The HA17901A series products are comparators designed for general purpose, especially for power control systems.
These ICs operate from a single power-supply voltage over a wide range of voltages, and feature a reduced powersupply current since the supply current is independent of the supply voltage.
These comparators have the merit which ground is included in the common-mode input voltage range at a singlevoltage power supply operation. These products have a wide range of applications, including limit comparators, simple
A/D converters, pulse/square-wave/time delay generators, wide range VCO circuits, MOS clock timers, multivibrators,
and high-voltage logic gates.

Note: If Input/Output terminals voltage over the absolute maximum ratings, there is possibility of mis-operation,
characteristics deterioration and destruction, because of the current’s flowing to parasitic diode in IC.
The Input/Output terminals are recommended to be protected with the clamp circuit which using the diode with
low forward voltage (like schottky barrier diode) when there is a possibility for the Input/Output terminals
voltage exceeds the absolute maximum ratings.

HA17901A Application Examples
The HA17901A houses four independent comparators in a single package, and operates over a wide voltage range at
low power from a single-voltage power supply. Since the common-mode input voltage range starts at the ground
potential, the HA17901A is particularly suited for single-voltage power supply applications. This section presents
several sample HA17901A applications.
1. Square-Wave Oscillator
The circuit shown in figure 1 has the same structure as a single-voltage power supply astable multivibrator. Figure
2 shows the waveforms generated by this circuit.

2. Pulse Generator
The charge and discharge circuits in the circuit from figure 1 are separated by diodes in this circuit. (See figure 3.)
This allows the pulse width and the duty cycle to be set independently. Figure 4 shows the waveforms generated by
this circuit.

3. Voltage Controlled Oscillator
In the circuit in figure 5, comparator A1 operates as an integrator, A2 operates as a comparator with hysteresis, and
A3 operates as the switch that controls the oscillator frequency. If the output Vout1 is at the low level, the A3 output
will go to the low level and the A1 inverting input will become a lower level than the A1 noninverting input. The
A1 output will integrate this state and its output will increase towards the high level. When the output of the
integrator A1 exceeds the level on the comparator A2 inverting input, A2 inverts to the high level and both the output
Vout1 and the A3 output go to the high level. This causes the integrator to integrate a negative state, resulting in its
output decreasing towards the low level. Then, when the A1 output level becomes lower than the level on the A2
noninverting input, the output Vout1 is once again inverted to the low level. This operation generates a square wave
on Vout1 and a triangular wave on Vout2.

the output goes to the high level.

5. Noninverting Comparator (with Hysteresis)
Assuming +VIN is 0 V, when VREF is applied to the inverting input, the output will go to the low level
(approximately 0 V). If the voltage applied to +VIN is gradually increased, the output will go high when the value of
the noninverting input, +VIN × R2/(R1 + R2), exceeds +VREF. Next, if +VIN is gradually lowered, Vout will be
inverted to the low level once again when the value of the noninverting input, (Vout – VIN) × R1/(R1 + R2), becomes
lower than VREF. With the circuit constants shown in figure 7, assuming VCC = 15 V and +VREF = 6 V, the following
formula can be derived, i.e. +VIN × 10 M/(5.1 M + 10 M) > 6 V, and Vout will invert from low to high when +VIN is
> 9.06 V.
(Vout − VIN) ×
R1
+ VIN < 6V
R1 + R 2
(Assuming Vout = 15V)
When +VIN is lowered, the output will invert from high to low when +VIN < 1.41 V. Therefore this circuit has a
hysteresis of 7.65 V. Figure 8 shows the input characteristics.

6. Inverting Comparator (with Hysteresis)
In this circuit, the output Vout inverts from high to low when +VIN > (VCC + Vout)/3. Similarly, the output Vout
inverts from low to high when +VIN < VCC/3. With the circuit constants shown in figure 9, assuming VCC = 15 V
and Vout = 15 V, this circuit will have a 5 V hysteresis. Figure 10 shows the I/O characteristics for the circuit in
figure 9.

In this circuit, the noninverting input will essentially beheld at the potential determined by dividing VCC with 100
kΩ and 10 kΩ resistors. When VIN is 0 V or higher, the output will be low, and when VIN is negative, Vout will
invert to the high level. (See figure 11.)
