Application

Figure 8 shows a typical application for the 17531A. 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 = 3.3 V), in order to ensure full enhancement of the high-side MOSFET channels.

5.TA = 25°C.
6.Terminal soldering temperature limit is for 10 seconds maximum duration. Not designed for immersion soldering.  xceeding these limits may cause malfunction or permanent damage to the device.


Description

The 17531A 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 17531A operates from 2.0 V to 8.6 V using the internal charge pump, with independent control of each H-Bridge via parallel MCU interface. The device features built-in shoot-through current protection and an undervoltage utdown function.

The 17531A has four operating modes: Forward, Reverse, Brake, and Tri-Stated (High Impedance). The 17531A has a low total RDS(ON) of 1.2 (max @ 25°C).

The 17531A efficiently drives many types of micromotors with low power dissipation owing to its low output resistance and high output slew rates. The H-Bridge outputs can be independently pulse width modulated (PWM'ed) at up to 200 kHz for speed/torque and current control.
