LMD18200T Pinout

LMD18200T Pin description

Pin 1, BOOTSTRAP 1 Input: Bootstrap capacitor pin for half H-bridge number 1. The recommended capacitor (10 nF) is connected between pins 1 and 2. Pin 2, OUTPUT 1: Half H-bridge number 1 output.

Pin 3, DIRECTION Input: This input controls the direction of current flow between OUTPUT 1 and OUTPUT 2 (pins 2 and 10) and, therefore, the direction of rotation of a motor load.

Pin 4, BRAKE Input: This input is used to brake a motor by effectively shorting its terminals. When braking is desired, this input is taken to a logic high level and it is also necessary to apply logic high to PWM input, pin 5. The drivers that short the motor is determined by the logic level at the DIRECTION input (Pin 3): with Pin 3 logic high, both current sourcing output transistors are ON; with Pin 3 logic low, both current sinking output transistors are ON. All output transistors can be turned OFF by applying a logic high to Pin 4 and a logic low to PWM input Pin 5; in this case, only a small bias current (approximately −1.5 mA) exists at each output pin.

Pin 5, PWM Input: How this input (and DIRECTION input, Pin 3) is used is determined by the format of the PWM Signal.

Pin 6, VS Power Supply Pin 7, GROUND Connection: This pin is the ground return, and is internally connected to the mounting tab.

Pin 8, CURRENT SENSE Output: This pin provides the sourcing current sensing output signal, which is typically 377 μA/A.

Pin 9, THERMAL FLAG Output: This pin provides the thermal warning flag output signal. Pin 9 becomes active low at 145°C (junction temperature). However, the chip won't turn off, though, until the junction temperature reaches 170°C.

Pin 10, OUTPUT 2: Half H-bridge number 2 output.

LMD18200T Overview

A 3A H-Bridge created for motion control applications is the LMD18200T. The LMD18200T is constructed utilizing a multi-technology process

 that integrates DMOS power devices with bipolar and CMOS control circuits on a single monolithic structure. The LMD18200T is perfect for 

driving DC and stepper motors and can handle peak output currents of up to 6A. The implementation of a novel circuit allows for low-loss 

output current sensing.

LMD18200T Features

Delivers Up to 3A Continuous Output

Operates at Supply Voltages Up to 55V

Low Ros(ON) Typically 0.33Q per Switch at 3A

TTL and CMOS Compatible Inputs

No“Shoot-Through" Current

Thermal Warning Flag Output at 145°C

Thermal Shutdown (Outputs Off) at 170°C

Internal Clamp Diodes

Shorted Load Protection

Internal Charge Pump with External Bootstrap Capability
