ATA6026

Features PWM and Direction-controlled Driving of Four Externally Powered NMOS Transistors Internal Charge Pump Provides Gate Voltages for High-side Drivers in Permanent ON Mode and Supplies the Gate of the External Battery Reverse Protection NMOS 5V Regulator With External Power Device (NPN) and Current Limitation Function Reset Derived From 5V Regulator Output Voltage Sleep Mode With Supply Current of Typical 35 µA, Wake-up by Signal on Pin EN or on SCI Interface (Pin /DATA) Window Watchdog; the Watchdog Time is Programmable by Choosing a Certain Value of the External Watchdog Capacitor CCWD and the External Watchdog Resistor RCWD Battery Overvoltage Protection and Battery Undervoltage Management Overtemperature Protection SCI Transceiver (Operating in Differential or Single-ended Mode) for Use at Battery Voltage Level Digital Control Block With the Control Pins EN, DIR, PWM Internal Low-power Regulator With Low-power Band Gap (Trimmed With Four Bits) to Guarantee Power Dissipation in Sleep Mode and to Guarantee Parameters for Wake-up H-bridge Motor Driver ATA6026 1. Description The ATA6026 is used to drive a continuous-current motor in a full H-bridge configuration. An external microcontroller controls the driving function of the ATA6026 by www.DataSheet4U.com providing a PWM signal and a direction signal, and allows the usage of the ATA6026 in a windshield wiper application, for example. The ATA6026 supports PWM and direction-controlled driving of ...
