Notes
1.VIN is the voltage level applied to any input terminal.
2.IO is measured as the load current flowing through the H-bridge.
3.TA = 25, pulse width < 10 ms at intervals > 0.2 seconds.
4.ESD1 testing is performed in accordance with the Human Body Model (CZAP = 100 pF, RZAP = 1500 ),  SD2 testing is performed in accordance with the Machine Model (CZAP = 200 pF, RZAP = 0 ).
5.Mounted on 37 x 50 Cu area (1.6 mm FR-4 PCB).
6.Maximum at TA = 25.
7.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.


Description

The 17550 is a monolithic quad H-Bridge power IC ideal for portable electronic applications containing tiny bipolar stepper motors and/or brush DC-motors powered by two-to-four cell NiCd/NiMH batteries.

The 17550 operates from 2.5 V to 5.5 V, with independent control of each H-Bridge via parallel 3.0 V or 5.0 V logic-compatible I/O. The 17550 features an on-board DC/DC boost converter that allows motor operation all the way down to 1.6 V (the boost converter supplies the gate-drive voltage for each of the four independent H-bridge output stages). Each output bridge of the 17550 has its own gate-drive and logic circuitry with built-in shoot-through current protection.

The 17550 has four operating modes: Forward, Reverse, Brake, and Tri-Stated (High Impedance). The 17550 has a low total RDS(ON) of 1.2 max @ 25 In addition, it can be set into a very low current-drain standby mode.

The H-Bridge outputs of the 17550  can be independently PWM'ed at up to 200 kHz for speed/torque and current control. The 17550 can efficiently drive many types of micromotors owing to its low output resistance and high output slew rates.
