Product Overview
SS8847E-ET-TP is LEADPOWER dual H-bridge motor driver IC. It drives two brushed DC motors or one bipolar stepper motor, as well as solenoid inductive loads. It supports 2.7V to 15V wide input voltage, with 1A continuous and 1.75A peak output current per channel. Built-in analog PWM circuit automatically limits winding current, reducing MCU calculation load. It integrates UVLO, OCP over-current and TSD thermal shutdown protection with over-temperature fault flag output. ETSSOP-16 package with bottom exposed pad optimizes heat dissipation. It supports both 3.3V and 5V MCU logic, widely used for office equipment, smart home actuators and small light industrial motion control modules.
Core Advantages
Dual Independent H-Bridge Drive Channels
Two complete H-bridge circuits on single chip, support one bipolar stepper motor or two separate brushed DC motors at the same time.
On-Chip PWM Automatic Current Limiting
Internal hardware chopping circuit monitors coil peak current without extra external sense peripheral design.
Low Power Static & Sleep Mode
Only 1.1mA normal quiescent current, 1μA ultra-low sleep current, extends battery-powered device working hours.
ETSSOP-16 Exposed Pad Heat Dissipation
Back thermal pad reduces chip junction temperature, stable continuous operation under rated output current.
Complete Multi-Layer Safety Protection
Integrated under-voltage lockout, over-current protection and thermal shutdown, with dedicated over-temperature fault output pin for system diagnosis.
Dual 3.3V / 5V Logic Compatibility
Input pins match mainstream MCU voltage levels, no extra level shift circuit required.

Frequently Asked Questions
Q1: Is SS8847E-ET-TP original LEADPOWER genuine chip?
A: All stock SS8847E-ET-TP are brand new original LEADPOWER semiconductors. Every batch has complete production traceability, shipped in factory original tape & reel packaging.
Q2: What does the “ET” suffix mean for this package?
A: ET stands for exposed thermal pad under ETSSOP-16 package. Soldering the pad to PCB copper ground plane improves heat dissipation for stable high-current output.
Q3: Can this chip drive bipolar stepper motors?
A: Yes, dual H-bridge design fully matches two phases of bipolar stepper motor, supports full-step, half-step and micro-stepping control via external MCU PWM signals.
Q4: Can I get PCB footprints, datasheet and tiered bulk prices?
A: Submit your purchase quantity via inquiry form, our sales team will send full technical documents and wholesale discount prices within 24 hours.
