17550 General 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 device 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 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 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.

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