HA17901, HA17339 Series
Quadruple Comparators
Description
The HA17901 and HA17339 series products are comparators designed for use in power or control systems.
These IC operate from a single power-supply voltage over a wide range of voltages, and feature a reduced
power-supply current since the power-supply voltage is determined independently.
These comparators have the unique characteristic of ground being included in the common-mode input
voltage range, even when operating from a single-voltage power supply. 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.

HA17901 Application Examples
The HA17901 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 HA17901 is particularly suited for single-voltage power supply applications.
This section presents several sample HA17901 applications.
HA17901 Application Notes
1. Square-Wave Oscillator
The circuit shown in figure one 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.

Figure 4 Operating Waveforms
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 circuit shown in figure 6 is a basic comparator. When the input voltage VIN exceeds the reference
voltage VREF, the output goes to the high level.

5. Noninverting Comparator (with Hysteresis)
Assuming +VIN is 0V, when VREF is applied to the inverting input, the output will go to the low level
(approximately 0V). 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 – V IN) × R1/(R1 + R2), becomes lower than VREF. With the circuit constants shown in figure 7,
assuming VCC = 15V and +VREF = 6V, the following formula can be derived, i.e. +VIN × 10M/(5.1M +
10M) > 6V, and Vout will invert from low to high when +VIN is > 9.06V.
(Vout – VIN) ×
R1
+ VIN < 6V
R1 + R2
(Assuming Vout = 15V)
When +VIN is lowered, the output will invert from high to low when +VIN < 1.41V. Therefore this
circuit has a hysteresis of 7.65V. 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 +V IN < VCC/3. With the circuit constants shown in figure 9,
assuming VCC = 15V and Vout = 15V, this circuit will have a 5V 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 100kΩ and 10kΩ resistors. When VIN is 0V or higher, the output will be low, and when VIN is
negative, Vout will invert to the high level. (See figure 11.)
