Figure 7 shows a typical application for the 17529. When applying the gate voltage to the CRES terminal from an external source, be sure to connect it via a resistor equal to, or greater than, RG = VCRES / 0.02 .
The internal charge pump of this device is generated from the VDD supply; therefore, care must be taken to provide sufficient gate-source voltage for the high-side MOSFETs when VM >> VDD (e.g., VM = 5.0 V, VDD = 3.0 V), in order to ensure full enhancement of the high-side MOSFET channels.

6.Soldering temperature limit is for 10 seconds maximum duration. Not designed for immersion soldering. Exceeding these limits may cause malfunction or permanent damage to the device.
DescriptionThe 17529 is a monolithic dual H-Bridge power IC ideal for portable electronic applications containing bipolar step motors and/or brush DC-motors (e.g., cameras and disk drive head positioners).
The 17529 operates from 2.0 V to 6.8 V, with independent control of each H-Bridge via parallel MCU interface (3.0 V- and 5.0 V-ompatible logic). The 17529 features on-board charge pump, as well as built-in shoot-through current protection and an undervoltage shutdown function.
The 17529 has four operating modes: Forward, Reverse, Brake, and Tri-Stated (High Impedance). The 17529 has a low total RDS(ON) of 1.2 (max @ 25).
The 17529's low output resistance and high slew rates provide efficient drive for many types of micromotors.
