PT5129 2CH H-Bridge Driver DESCRIPTION FEATURES The PT5129 motor driver provides 2 Full-On Driver H-Bridge channels. This driver features wide range operating from 2.0V and low power consumption by fast switching speed in a compact surface mount package. Range of motor power supply voltage: -Control (VCC): 2.5V to 5.5V - Motor (VM): 2.0V to 16V High DC output current: Max.=1.8A Ultra low RDSON(TOP+BOT): 0.42ΩTYP@25°C Charge pump-less type with p-channel DMOS for the upper side transistor Low current consumption when power-down: <1μA @25°C High-speed switching: -Turn On Time: 350ns, Turn Off Time: 125ns (Typ.) Operating temperature range: -30℃ to +85℃ Built-in protection circuits - Under Voltage Lock Out (UVLO) - Thermal Shut Down (TSD) APPLICATIONS Single-lens reflex Mobile system Home appliance Amusement system BLOCK DIAGRAM Tel: 886-66296288‧Fax: 886-29174598‧ http://www.princeton.com.tw‧2F, 233-1, Baociao Rd., Sindian Dist., New Taipei City 23145, Taiwan PT5129 APPLICATION CIRCUIT Note: VM pin groups 9, 10 and 21, 22 are recommended to be short-circuited on the PCB pattern. If cannot,check into transitional characteristics of total application circuit including two motors. Through low impedance materials, the possibility of causing some unexpected malfunctions is incontrovertible.
