NJU7381A

NJU7381A LOW VOLTAGE OPERATION DUAL H BRIDGE DRIVER ■ GENERAL DESCRIPTION The NJU7381A is a dual H-bridge driver IC that features low voltage operation and low quiescent current. The control method is 2 logic Inputs (2-IN) that includes standby mode. The independent comparator circuit can be used for position sensing signal processing and the others. Small package makes the NJU7381A suitable for small stepper motor and DC motor, such as portable applications. ■ FEATURES Supply Voltage : VDD=1.8V to 5.5V Output Current : IO=200mA (Continuous) IO=400mA (Peak) Output ON Resistance : RO(H+L)=1.25Ω typ. at VDD=3.3V RO(H+L)=1.95Ω typ. at VDD=1.8V Low Quiescent Current : 60µA typ. at VDD=3.3V 2 Logic Inputs Control (2-IN) Stand-by Function (At no-input signal) Built-in Comparator Circuit Protection Circuit : Thermal Shutdown Circuit (TSD) Package Outline : EQFN16-JE, SSOP16 ■ BLOCK DIAGRAM VDD ■ PACKAGE OUTLINE NJU7381AMJE (EQFN16-JE) NJU7381AV (SSOP16) INA1 INA2 INB1 INB2 GND COMP + COMP - Control Logic TSD Stepper OUTA1 Motor M OUTA2 OUTB1 OUTB2 COMP OUT Ver.2015-04-06 -1- NJU7381A ■ PIN CONFIGURATION EQFN16-JE 12 11 10 9 13 14 15 16 1234 Top View 8 7 6 5 SSOP16 1 16 2 15 3 14 4 13 5 12 6 11 7 10 89 Top View 1234 16 5 15 6 SUB 14 7 13 8 12 11 10 9 Bottom View ■ PIN DESCRIPTION PIN No. EQFN16 SSOP16 12 23 3,11 4,12 45 56 67 7,15 8,16 89 9 11 10 10 12 13 13 14 16 SUB 14 15 1 - PIN NAME INB1 INB2 VDD INA2 INA1 OUTA2 GND OUTA1 COMP OUT NC COMP+ CO...
