When designing a circuit, ensure that the maximum junction temperature, TjMAX = 150°C, is not exceeded when the IC is used. Avoid using the IC in abnormal conditions that would cause the Tj to exceed 150°C, even though the heat protection circuit of the IC will continue to operate in such conditions. Note 2: When mounted on a board (50 mm × 50 mm × 1.6 mm, Cu area: 50%) The absolute maximum ratings of a semiconductor device are a set of specified parameter values that must not be exceeded during operation, even for an instant. If any of these ratings are exceeded during operation, the electrical characteristics of the device may be irreparably altered, in which case the reliability and lifetime of the device can no longer be guaranteed. Moreover, any exceeding of the ratings during operation may cause breakdown, damage and/or degradation in other equipment. Applications using the device should be designed so that no maximum rating will ever be exceeded under any operating condition. Before using, creating and/or producing designs, refer to and comply with the precautions and conditions set forth in this document.

To prevent shoot-through current caused by simultaneous conduction of upper and lower transistors in the output stage, a dead time is internally generated for 300 ns (target spec) when the upper and lower transistors are being switched. Therefore synchronous rectification for high efficiency in PWM current control can be achieved without an off-time generated via an external input. Even for toggling between CW and CCW modes, and CW (CCW) and short brake modes, no off-time is required due to the internally generated dead time. VCC OUT1 VCC M OUT1 VCC M OUT1 RS RS RS PWM ON → OFF t2 = 300 ns (typ.) PWM ON t1 PWM OFF t3 VCC OUT1 M VCC OUT1 M M RS RS PWM OFF → ON t4 = 300 ns (typ.)

After a further four clock signals in discharge mode, VRS is compared with Vref. If VRS < Vref, the IC operates in charge mode until VRS reaches Vref.

Internal oscillation frequency (fosc) The internal oscillation frequency is approximated by the formula below: fosc = 1 / (0.523 × (Cosc × 3700 + Cosc × 600)). 12 2007-3-22 TB6562ANG/AFG Reference Voltage Generator The current value at 100% is determined by applying voltage at the Vref pin. The value can be calculated as follows: IO (100%) = Vref × 1/10 × 1/RS[A] (X1 = X2 = L) VCC Control circuit OUT1 X1 X2 OUT2 M Decoder IO 1/10 1/15 1/30 RS Vref IO Thermal Shutdown Circuit (TSD) The IC incorporates a thermal shutdown circuit. When the junction temperature (Tj) reaches 160°C (typ.), the output transistors are turned off. After 50 μs (typ.), the output transistors are turned on automatically. The IC has 40°C temperature hysteresis. TSD = 160°C (target spec) ΔTSD = 40°C (target spec) Overcurrent Protection Circuit (ISD) The IC incorporates an overcurrent protection circuit to detect voltage flowing through the output transistors. The overcurrent threshold is 2.5 A (typ.). Currents flowing through the eight output transistors are monitored individually. If overcurrent is detected in at least one of the transistors, all transistors are turned off. The IC incorporates a timer to count the 50 μs (typ.) for which the transistors are off. After the 50 μs, the transistors are turned on automatically. If an overcurrent occurs again, the same operation is repeated. To prevent false detection due to glitches, the circuit turns off the transistors only when current exceeding the overcurrent threshold flows for 10 μs or longer. ILIM Output current 0 50 μs (typ.) 10 μs (typ.) 50 μs (typ.) 10 μs (typ.) Not detected The target specification for the overcurrent limiter value (overcurrent threshold) is 2.5 A (typ.), and varies in a range from approximately 1.5 A to 3.5 A. These protection functions are intended only as a temporary means of preventing output short circuits or other abnormal conditions and are not guaranteed to prevent damage to the IC. If the guaranteed operating ranges of this product are exceeded, these protection features may not operate and some output short circuits may result in the IC being damaged. The overcurrent protection feature is intended to protect the IC from temporary short circuits only. Short circuits persisting over long periods may cause excessive stress and damage the IC. Systems should be configured so that any overcurrent condition will be eliminated as soon as possible. 13 2007-3-22 TB6562ANG/AFG Application Circuit The application circuit below is for reference only and requires thorough evaluation at the mass production design stage.

Test Circuits Components in the test circuits are used only to obtain and confirm the device characteristics. These components and circuits are not guaranteed to prevent malfunction or failure from occurring in the application equipment. IC Usage Considerations Notes on handling of ICs [1] The absolute maximum ratings of a semiconductor device are a set of ratings that must not be exceeded, even for a moment. Do not exceed any of these ratings. Exceeding the rating(s) may cause the device breakdown, damage or deterioration, and may result injury by explosion or combustion. [2] Use an appropriate power supply fuse to ensure that a large current does not continuously flow in case of over current and/or IC failure. The IC will fully break down when used under conditions that exceed its absolute maximum ratings, when the wiring is routed improperly or when an abnormal pulse noise occurs from the wiring or load, causing a large current to continuously flow and the breakdown can lead smoke or ignition. To minimize the effects of the flow of a large current in case of breakdown, appropriate settings, such as fuse capacity, fusing time and insertion circuit location, are required. [3] If your design includes an inductive load such as a motor coil, incorporate a protection circuit into the design to prevent device malfunction or breakdown caused by the current resulting from the inrush current at power ON or the negative current resulting from the back electromotive force at power OFF. IC breakdown may cause injury, smoke or ignition. Use a stable power supply with ICs with built-in protection functions. If the power supply is unstable, the protection function may not operate, causing IC breakdown. IC breakdown may cause injury, smoke or ignition. [4] Do not insert devices in the wrong orientation or incorrectly. Make sure that the positive and negative terminals of power supplies are connected properly. Otherwise, the current or power consumption may exceed the absolute maximum rating, and exceeding the rating(s) may cause the device breakdown, damage or deterioration, and may result injury by explosion or combustion. In addition, do not use any device that is applied the current with inserting in the wrong orientation or incorrectly even just one time. 17 2007-3-22 TB6562ANG/AFG Points to remember on handling of ICs (1) Over current Protection Circuit Over current protection circuits (referred to as current limiter circuits) do not necessarily protect ICs under all circumstances. If the Over current protection circuits operate against the over current, clear the over current status immediately. Depending on the method of use and usage conditions, such as exceeding absolute maximum ratings can cause the over current protection circuit to not operate properly or IC breakdown before operation. In addition, depending on the method of use and usage conditions, if over current continues to flow for a long time after operation, the IC may generate heat resulting in breakdown. (2) Thermal Shutdown Circuit Thermal shutdown circuits do not necessarily protect ICs under all circumstances. If the thermal shutdown circuits operate against the over temperature, clear the heat generation status immediately. Depending on the method of use and usage conditions, such as exceeding absolute maximum ratings can cause the thermal shutdown circuit to not operate properly or IC breakdown before operation. (3) Heat Radiation Design In using an IC with large current flow such as power amp, regulator or driver, please design the device so that heat is appropriately radiated, not to exceed the specified junction temperature (TJ) at any time and condition. These ICs generate heat even during normal use. An inadequate IC heat radiation design can lead to decrease in IC life, deterioration of IC characteristics or IC breakdown. In addition, please design the device taking into considerate the effect of IC heat radiation with peripheral components. (4) Back-EMF When a motor rotates in the reverse direction, stops or slows down abruptly, a current flow back to the motor’s power supply due to the effect of back-EMF. If the current sink capability of the power supply is small, the device’s motor power supply and output pins might be exposed to conditions beyond maximum ratings. To avoid this problem, take the effect of back-EMF into consideration in system design. 18 2007-3-22 TB6562ANG/AFG RESTRICTIONS ON PRODUCT USE 070122EBA_R6 • The information contained herein is subject to change without notice. 021023_D • TOSHIBA is continually working to improve the quality and reliability of its products.
