17529 General Description

The 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 device 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.

17529 Typical Application

TYPICAL APPLICATION
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, R_G = V_CRES/ 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 V_M >> V_DD (e.g., V_M = 5.0 V, VDD = 3.0 V), in order to ensure full enhancement of the high-side MOSFET channels.
