Notes
3.Transient condition within 500 ms.
4.Continuous output current must not be exceeded and at operating junction temperature below 150°C.
5.Peak time is for 10 ms pulse width at 200 ms intervals.
6.ESD testing is performed in accordance with the Human Body Model (CZAP = 100 pF, RZAP = 1500 ), and the Machine Model (CZAP = 200 pF, RZAP = 0 ).
7.Terminal 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.
8.For cases using SEMI G38-87, JEDEC JESD51-2, JESD51-3, JESD51-5, single layer PCB mounting without thermal vias.
9.For cases using SEMI JEDEC JESD51-6, JESD51-5, JESD51-7, 2S2P PCB mounting with 4 thermal vias.
DescriptionThe 17C724 is a compact monolithic dual channel H-Bridge power IC, ideal for portable electronic applications containing bipolar stepper motors or brush DC motors such as those used in camera lenses and shutters.
The 17C724 can operate efficiently with supply voltages from 2.7 V to 5.5 V and can provide continuous motor drive currents of 0.4 A with low RDS(ON) of 1.0 . It is easily interfaced to low-cost MCUs via parallel 3.0 V- or 5.0 V-compatible logic and has built-in shoot-through current protection circuit and undervoltage detector to avoid malfunction.
The 17C724 has four output control modes: Forward, Reverse, Brake, and Tri-State (High Impedance). The H-bridge outputs are designed to be independently PWM'ed at up to 200 kHz for speed/torque and current control.
