Note that connecting to the 5 V or 3.3 V supply without a pull-up even though a 1 M pull-up resistor is built-in at F resistor disables the TSD function (however, low-side UVLO protection and OCP function remain active). O * To avoid malfunctions resulting from noise interference, place a 0.01 to 0.1 F ceramic capacitor (C1) between the F and COM2 pins. * To avoid malfunctions resulting from noise interference, the traces must be as short as possible between the IC and the bootstrap capacitors, CBOOTx (1 F). * One of the bootstrap capacitors for the W phase can be populated between pin 24 (W1) and pin 25 (VB31). Also, because pin 27 (VB32) and pin 25 are internally connected, pin 27 can be left open. * To avoid malfunctions resulting from noise interference, place a 0.01 to 0.1 F ceramic capacitor between the VCC1 and COM1 (C2), as well as the VCC2 and COM2 (C3) pins. Also, the traces between them must be as short as possible. * To avoid malfunctions resulting from noise interference, the traces between the current sense resistor RS, which is placed between the LS and COM2 pins, and the IC must be as short and wide as possible. * If the generated voltage on the LS pin exceeds 7 V, add a Zener diode between the LS and COM2 pins.

Circuit designs that embody these components must conform with applicable safety requirements. Precautions must be taken to prevent accidental contact with power-line potentials. Do not connect grounded test equipment. The use of an isolation transformer is recommended during circuit development and breadboarding. Because reliability can be affected adversely by improper storage environments and handling methods, please observe the following cautions. Cautions for Storage * Ensure that storage conditions comply with the standard temperature (5C to 35C) and the standard relative humidity (around 40 to 75%); avoid storage locations that experience extreme changes in temperature or humidity. * Avoid locations where dust or harmful gases are present and avoid direct sunlight. * Reinspect for rust on leads and solderability of products that have been stored for a long time. Cautions for Testing and Handling When tests are carried out during inspection testing and other standard test periods, protect the products from power surges from the testing device, shorts between adjacent products, and shorts to the heatsink. Remarks About Using Silicone Grease with a Heatsink * When silicone grease is used in mounting this product to a heatsink, it shall be applied evenly and thinly. If more silicone grease than required is applied, it may produce stress. * Volatile-type silicone greases may permeate the product and produce cracks after long periods of time, resulting in reduced heat radiation effect, and possibly shortening the lifetime of the product. * Our recommended silicone greases for heat radiation purposes, which will not cause any adverse effect on the product life, are indicated in the following table: Type Suppliers G746 Shin-Etsu Chemical Co., Ltd. YG6260 Momentive Performance Materials, Inc. SC102 Dow Corning Toray Silicone Co., Ltd. Soldering * When soldering the products, please be sure to minimize the working time, within the following limits: 2605C 10 s 3805C 5 s, using soldering iron * Soldering iron should be at a distance of at least 1.5 mm from the body (resin case) of the products Electrostatic Discharge * When handling the products, operator must be grounded. Grounded wrist straps worn should have at least 1 M of resistance to ground to prevent shock hazard. * Workbenches where the products are handled should be grounded and be provided with conductive table and floor mats. * When using measuring equipment such as a curve tracer, the equipment should be grounded. * When soldering the products, the head of soldering irons or the solder bath must be grounded in other to prevent leak voltages generated by them from being applied to the products. * The products should always be stored and transported in our shipping containers or conductive containers, or be wrapped in aluminum foil.
