ADE-207-111B (Z)

3rd Edition

July 1996

Description

The HA13536F is a 3-phase brushless DC motor driver IC with digital speed control. It is being developed
for direct drive of the spindle motor of 5 V floppy disk drives with a height of 3/4" or less. It has the follow­ing functions and features.

Functions

• 1.0 A per phase, 3-phase drive circuit (current driver)

• Digital speed control circuit

• FG Amp

• Index circuit

• Current limiter circuit

• Over-temperature shutdown circuit (OTSD)

Features

• Low saturation voltage, typically 1.15 V (at 0.7 A)

• Soft switching drive circuit

• No need for an output snubber circuit

2. The current limiter operates according to the following formula:

I

OMAX =

where Vref1 is the current limiter reference voltage (see Electrical Characteristics)

3. The burst time t1 is defined as follows:
t1 ≈ – Ct × Rt1’ × ln (1 – Vth1 (L) / Vreg) (RPM select input low)

t1 ≈ – Ct × Rt1’ × ln (1 – Vth1 (H) / Vreg) (RPM select input high)

where Rt1’ is resistance value inter 3 to 4 pin.

4. Place as close to the IC as possible.

5. Determine C102 and C103 according to the following formulas:

where Vth2 is the threshold voltage (see Electrical Characteristics).
Rt2’ : Rt1 (max) + Rt2

7. If the circuit is affected by noise, a large capacitance value should be set.
