TA8429HQ Datasheet | Toshiba

Features Weight : 4.04 g (typ.) z Output current of up to 3.0 A (AVE.) and 4.5 A (PEAK) z Four different modes (forward rotation, reverse rotation, stop, and brake) are supported. A counter-electromotive force absorber diode is also incorporated. z Stand-by mode available: IST ≤ 100 μA z Built-in thermal shutdown and short circuit protection circuits z HZIP power package sealed z Wide range of operating voltage: VCC = 7 to 27 V VS = 0 to 27 V - Please consider the internal loss (Vsat) to operate the IC though minimum VS is defined zero. Terminals of TA8429 written below are sensitive to electrostatic discharge. When handling this product, ensure that the environment is protected against electrostatic discharge by using an earth strap, a conductive mat and an ionizer. Ensure also that the ambient temperature and relative humidity are maintained at reasonable levels. Terminals which are sensitive to electrostatic discharge: No. 1, 2, and 12. The IC should be installed correctly. Otherwise, the IC or peripheral parts and devices may be degraded or permanently damaged. The TA8429HQ is a Sn-plated product. (The Pb-containing materials with a high melting point that are exempted from Ro HS directives are used inside the IC.) The following conditions apply to solderability: - Solderability 1. Use of Sn-37Pb solder bath - solder bath temperature = 230°C - dipping time = 5 seconds - number of times = once - use of R-type flux 2. Use of Sn-3.0Ag-0.5Cu solder bath - solder bath temperature = 245°C - dipping time = 5 seconds - the number of times = once - use of R-type flux 2010-02-23 Block Diagram TA8429H/HQ Pin Function Pin No. 1 2 3 5 6 7 8 9 10 11 12 Symbol IN1 IN2 N.C OUT1 N.C GND N.C OUT2 N.C VS VCC ST Functional Description These pins receive inputs for controlling the state of the outputs.
