Description
The HA17901 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.

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 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 – VIN) × 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

(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 +VIN < 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.)
