1. Switching regulator oscillation circuit (PWM generation circuit)
1-1. Oscillation circuit (40 to 50kHz max.)
Figure 1 shows the oscillation circuit that generates the
triangular waves. The oscillation frequency for this circuit
is detemined by the following equation (with VH=7V typ.)

of variation in the IC’s internal resistance.

2. Position detection circuit (Hall element input circuit)
The position detection circuit is a differential amp with hysteresis (38mV typ.). For the operating DC level,
use within the common-mode phase input voltage range (1.5 to VH–1.8V). Also it is recommended that the
input level is at least three times (150 to 200mVp-p) the hysteresis.

3. VH power supply circuit
The VH power supply pins can be used to from the internal power supply or an external power supply.
When using the internal power supply, the internal logic operates with VH=7V typical (VCC=24V). When using
an external power supply, set VCC=VH=5V and operate the internal logic at 5V.

4. Current limiter circuits
4-1. Current limiter 1

The current is limited by moving the sink side transistor from saturated to undaturated, so ASO can be
a problem.

I =

VRf1

(A)

R

f

Therefore, design so that as much as possible current limiter 1 is not triggered.
Also, take particular care not to exceed the maximum output current (2.5A) when current limiter 1 is
triggered.

4-2. Current limiter 2

This circuit limits the current by lowering the PWM output duty, thus lowering the VM voltage.
When current limiter 2 is triggered, the output current is no greater than 2A.

VRf2

I =

R

f

When not controlling the PWM, add a current limiter to the VM power supply. (A current setting no
greater than 60% to 70% of the current value of current limiter 1 and a short delay time are
recommended.)

5. Protection circuits
5-1. Overvoltage protection circuit

If the voltage at the VCC pin rises above the regulated votlage (38V), PWM output is inhibited and the
sink side output driver is switched off.

5-2. Low-votlage protection circuit

If the voltage at the VCC pin falls below the regulated voltage, just as in 5-1, PWM output is inhibited
and the sink side output driver is switched off.

5-3. Thermal shutdown circuit

If the junction temperature rises above the regulated temperature, just as in 5-1, PMW output is
inhibited and the sink output driver is switched off.
