DESCRIPTION
The UC1637 is a pulse width modulator circuit intended to be used for a variety of PWM motor drive and
amplifier applications requiring either uni-directional or bi-directional drive circuits. When used to replace
conventional drivers, this circuit can increase efficiency and reduce component costs for many applications. All
necessary circuitry is included to generate an analog error signal and modulate two bi-directional pulse train
outputs in proportion to the error signal magnitude and polarity.
This monolithic device contains a sawtooth oscillator, error amplifier, and two PWM comparators with ±100-mA
output stages as standard features. Protection circuitry includes under-voltage lockout, pulse-by-pulse current
limiting, and a shutdown port with a 2.5-V temperature compensated threshold.
The UC1637 is characterized for operation over the full space temperature range of –55°C to 125°C.

FUNCTIONAL DESCRIPTION
The following is a description of each of the functional blocks shown in the Functional Block Diagram.
Oscillator
The oscillator consists of two comparators, a charging and discharging current source, a current source set
terminal, ISET, and a flip-flop. The upper and lower threshold of the oscillator waveform is set externally by
applying a voltage at pins +VTH and -VTH respectively. The +VTH terminal voltage is buffered internally and also
applied to the ISET terminal to develop the capacitor charging current through RT. If RT is referenced to -VS as
shown in Figure 1, both the threshold voltage and charging current will vary proportionally to the supply
differential, and the oscillator frequency will remain constant. The triangle waveform oscillator's frequency and
voltage amplitude are determined by the exernal components using the formulas given in Figure 1.

PWM Comparators
Two comparators are provided to perform pulse width modulation for each of the output drivers. Inputs are
uncommitted to allow maximum flexibility. The pulse width of the outputs A and B is a function of the sign and
amplitude of the error signal. A negative signal at -AIN and +BIN will lengthen the high state of output A and
shorten the high state of output B. Likewise, a positive error signal reverses the procedure. Typically, the
oscillator waveform is compared against the summation of the error signal and the level set on -BIN and +AIN.

MODULATION SCHEMES
Case A Zero Deadtime (Equal voltage on -BIN and +AIN)
In this configuration, maximum holding torque or stiffness and position accuracy is achieved. However, the power
input into the motor is increased. Figure 3 (A) shows this configuration.
Case B Small Deadtime (Voltage on -BIN > +AIN)
A small differential voltage between -BIN and +AIN provides the necessary time delay to reduce the chances of
momentary short circuit in the output stage during transitions, especially where power-amplifiers are used. Refer
to Figure 3 (B).
Case C Increased Deadtime and Deadband Mode (Voltage on -BIN > +AIN)
With the reduction of stiffness and position accuracy, the power input into the motor around the null point of the
servo loop can be reduced or eliminated by widening the window of the comparator circuit to a degree of
acceptance. Where position accuracy and mechanical siffness is unimportant, deadband operation can be used.
This is shown in Figure 3 (C).

Ouput Drivers
Each output driver is capable of both sourcing and sinking 100 mA steady state and up to 500 mA on a pulsed
basis for rapid switching of either POWERFET or bipolar transistors. Output levels are typically -VS+0.2 V at 50
mA low level and +VS-2 V at 50 mA high level.
Error Amplifier
The error amplifier consists of a high slew rate (15 V/ms) op-amp with a typical 1-MHz bandwidth and low output
impedance. Depending on the ±VS supply voltage, the common mode range and the voltage output swing is
within 2 V of the VS supply.
Under-Voltage Lockout
An under-voltage lockout circuit holds the outputs in the low state until a minimum of 4 V is reached. At this point,
all internal circuitry is functional and the output drivers are enabled. If external circuitry requires a higher starting
voltage, an over-riding voltage can be programmed through the shutdown terminal as shown in Figure 4.
Shutdown Comparator
The shutdown terminal may be used for implementing various shutdown and protection schemes. By pulling the
terminal more than 2.5 V below VIN, the output drivers will be enabled. This can be realized using an open
collector gate or NPN transistor biased to either ground or the negative supply. Since the threshold is
temperature stabilized, the comparator can be used as an accurate low voltage lockout (Figure 4) and/or delayed
start as in Figure 5. In the shutdown mode the outputs are held in the low state.

Current Limit
A latched current limit amplifier with an internal 200-mV offset is provided to allow pulse-by-pulse current limiting.
Differential inputs will accept common mode signals from -VS to within 3 V of the +VS supply while providing
excelent noise rejection. Figure 6 shows a typical current sense circuit.
