NJM37770 STEPPER MOTOR DRIVER ■ GENERAL DESCRIPTION NJM37770 is a stepper motor driver, which consists of a LS-TTL compatible logic input stage, a current sensor, a monostable multivibrator and a high power H-bridge output stage. The NJM37770 is a high power version and pincompatible with the NJM37717 and also NJM37770 is a high voltage version with NJM3770A. Two NJM37770 and a small number of external components form a complete control and drive unit stepper motor systems. ■ FEATURES ● Half-step and full-step operation ● Switched mode bipolar constant current drive ■ PACKAGE OUTLINE NJM37770E2 ( SOP20-E2 ) ● Wide range of current control ● Wide voltage range ● Thermal overload protection ● Packages 5 to 1500mA 10 to 60 V SOP20-E2 JEDEC 300mil ■ BLOCK DIAGRAM Figure 1.
