LA6588MC

Ordering number : ENA2020 Monolithic Linear IC LA6588MC Overview 24V power supply, BTL output linear drive Single-phase Fan Motor IC The LA6588MC is a Single-phase bipolar fan motor IC for 24V power supply. BTL output linear drive ensures highly-efficient, energy-saving, and silent drive while suppressing the ineffective current. Lock protection and lock signal circuit are incorporated, proving most suitable for consumer equipment power supply, OA equipment and car audio system, etc which require high reliability and low noise. Functions • Single-phase full-wave linear drive by BTL output (gain resistance 500 to 360k, 57dB) : No switching noise, which is most favorable for use in equipment requiring silent operation, such as consumer equipment power supply, car audio system, etc. • Operable at low voltage and over a wide operation voltage range (8 to 26.4V) • Low saturation output (Upper + lower saturation voltages: VOsat (total) = 1.1V typ, IO = 200mA) : High coil efficiency and small current drain. Small heat generation from IC itself • Lock protection and automatic return circuits incorporated • Lock protection signal output (L during rotation, H at stop, open collector output) • Output (Rotation detection output: Open collector output) • Hall bias incorporated (VHB = 1.5V) • Heat protection circuit :The heat protection circuit suppresses the drive current to prevent burn or damage of IC when the large current flows due to output short-circuit and the IC chip temperature exceeds 180°C. • Small package with high heat capacity (MFP10SK) Pin- compatible silent series (5V/12V/24V products) Specifications Absolute Maximum Ratings at Ta = 25°C Parameter Supply voltage Output current Output withstand voltage Symbol VCC max IOUT max VOUT max Conditions Ratings 28 0.8 28 Unit V A V Continued on next page.

Similarly, Cr is necessary to enhance the reliability when there is no capacitor near the fan power line. *2: When taking Hall bias from VCC, carry out bias to VCC with resistor R1 as shown in the figure. Linear drive is achieved through voltage control of the coil by amplifying the Hall output. With large Hall element output, the start performance and efficiency are improved. Noise can be reduced further by adjusting the Hall element. *3: When the Hall bias is taken from the HB pin, constant-voltage bias is made with about 1.5V. Therefore, the Hall element can provide the output satisfactory in temperature characteristics. *4: Keep this open when not using. *5: When the wiring from the Hall output to IC Hall input is long, noise may be carried through the wiring. In this case, insert the capacitor as shown in the figure.
