1. Introduction
Double H driver module uses ST L298N dual full-bridge driver, an integrated
monolithic circuit in a 15- lead Multiwatt and PowerSO20 packages. It is a high voltage,
high current dual full-bridge driver designed to accept standard TTL logic levels and
drive inductive loads such as relays, solenoids, DC and stepping motors. Two enable
inputs are provided to enable or disable the device independently of the input signals.
The emitters of the lower transistors of each bridge are connected together and the
corresponding external terminal can be used for the con-nection of an external sensing
resistor. An additional supply input is provided so that the logic works at a lower
voltage.
Specification:
 Driver: L298N
 Driver power supply: +5V/DC to +35V/DC
 Driver Io: 2A
 Logic power output Vss: +5/DC to 7V/DC (internal supply +5V/DC)
 Logic current: 0 - 36mA
 Controlling level: Low -0.3V/DC to 1.5V/DC, high: 2.3V/DC to Vss
 Enable signal level: Low -0.3V/DC to 1.5V/DC, high: 2.3V/DC - Vss
 Max power: 25W (Temperature 75 cesus)
 Working temperature: -25℃ to +130℃
