Product details
Overview
UPD16879GS-BGG-A from Renesas Electronics is a monolithic quad H-bridge stepper motor driver IC with CMOS control and MOSFET output stages, delivering 64-step microstepping, serial-data motor control (8 bits × 13 bytes), and dual-motor drive capability. It operates from 2.7 V to 5.5 V control supply and 4.0 V to 11 V motor supply, with ±0.1 A/ch DC drive current and 3 mA typical operating current - optimized for camcorder mechanism control.
For engineers reviewing the UPD16879GS-BGG-A datasheet, UPD16879GS-BGG-A pinout, UPD16879GS-BGG-A application, or UPD16879GS-BGG-A equivalent, key selection considerations include its 38-pin shrink SOP package, current-controlled microstepping architecture, serial interface timing (SCLK up to 5 MHz, VD sync), and dual-channel independent current setting via EVR and serial data.
Technical Context
The UPD16879GS-BGG-A integrates four independent H-bridge drivers (two per motor channel: α and β), each with external sense-resistor feedback (FBA/FBB/FBC/FBD pins) and filter capacitor connections (FILA–FILD). Its internal oscillator (4.5 MHz typical, adjustable via COSC) generates PWM chopping frequencies from 35.71 kHz to 225 kHz, programmable via the 3rd byte of serial input.
Motor control is fully serial: 13-byte command frame configures first-point wait, magnetize delay, enable/rotation direction, per-channel current (11–31 code → 50–250 mV EVR), pulse count (0–1020), and pulse cycle (1–65535 × 222 ns). The IC supports power-save mode (100 µA VDD current with fCLK off) and provides real-time monitoring via EXTα/EXTβ and open-drain EXP0/EXP1 outputs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply voltage (VDD) | 2.7 V to 5.5 V - powers CMOS logic; enables low-voltage operation in battery-powered camcorders. |
| Motor supply (VM) | 4.0 V to 11 V - supports wide-range brushed/stepper motor operation; multiple VM pins (VM1–VM4) require common connection. |
| Drive current (DC) | ±0.1 A per channel - sufficient for small-form-factor stepper motors; limited by RON ≈ 6 Ω at 25°C. |
| Microstepping resolution | 64-step - reduces vibration and audible noise in precision positioning applications like lens focus/zoom mechanisms. |
| Serial interface | 8-bit × 13-byte frame, LSB-first, SCLK ≤ 5 MHz - enables compact MCU-to-driver communication with minimal GPIO usage. |
| Power consumption (operating) | 3 mA max at VDD = 3 V - enables extended battery life; drops to 100 µA in power-save mode with fCLK disabled. |
| Chopping frequency range | 35.71 kHz to 225 kHz - selectable via 6-bit data; higher frequencies reduce audible coil whine but increase switching loss. |
Pinout & Package
Package: 38-pin plastic shrink SOP (7.62 mm width, 300 mil), surface-mount compatible with standard reflow profiles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| LGND (1), PGND (20) | Control GND / Power GND | Separate ground returns minimize noise coupling between logic and high-current H-bridge paths. |
| VDD (8), VM1–VM4 (9,13,23,27) | Control supply / Motor supply inputs | All VM pins must be shorted externally; VDD powers only logic; VM powers all four H-bridges. |
| A1/A2/B1/B2 (24,26,28,30), C1/C2/D1/D2 (14,16,10,12) | H-bridge output terminals | Two independent dual-H-bridge sets: α channel (A/B) and β channel (C/D); each drives one bipolar stepper phase pair. |
| FBA/FBB/FBC/FBD (25,29,15,11) | Current sense resistor connections | Connect external 6.8 Ω resistors to set peak current; voltage drop feeds internal current regulation loop. |
| SCLK/SDATA/LATCH/VD/VD (35,34,33,31,32) | Serial interface and video sync inputs | VD pins accept video sync signal for motion-synchronized stepping; LATCH latches 13-byte frame on falling edge. |
| EXTα/EXTβ (21,22), EXP0/EXP1 (17,18) | Internal status monitor outputs | EXTα/β provide logic-level channel activity; EXP0/1 are open-drain for external pull-up and flexible signaling. |
Key Features
| Feature | Design Value |
|---|---|
| Quad H-bridge MOSFET output stage | Four independent, low-RON (6 Ω typ) bridges eliminate need for external transistors and reduce board space vs. discrete solutions. |
| 64-step current-controlled microstepping | Enables smooth, low-vibration motion in optical zoom/focus systems without external microstepping controller. |
| Serial 13-byte configuration interface | Reduces required MCU I/O count to just 4 pins (SCLK, SDATA, LATCH, VD); eliminates parallel bus routing and address decoding. |
| Dual independent motor control | Simultaneously drives two 2-phase stepper motors (e.g., lens zoom + focus) with separate current, pulse count, and direction settings. |
| Integrated power-save mode | Reduces VDD current from 3 mA to 100 µA during idle, extending battery life in portable camcorder applications. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar stepper motor driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TB6600HG | Higher voltage (45 V VM), higher current (3.5 A/ch), parallel interface; no microstepping or serial control. | Industrial CNC stages, not portable consumer devices; requires external current sensing and microstepping logic. | Select when >1 A drive current or >11 V motor supply is needed; avoid for space-constrained, low-power designs. |
| LV8731V | 36-pin HTSSOP, 2.5 A/ch, 64-step microstepping, SPI interface; integrated current DAC eliminates external EVR resistor. | Modern camcorders and DSLR lens modules; supports higher torque motors and faster SPI clocking (10 MHz). | Prefer for new designs requiring higher current or simplified layout; UPD16879GS-BGG-A remains viable for legacy cost-sensitive builds. |
Compared with TB6600HG and LV8731V, the UPD16879GS-BGG-A offers uniquely low quiescent current (100 µA) and compact 38-pin shrink SOP packaging ideal for legacy camcorder platforms, while trading off maximum current and modern interface speed for proven reliability and minimal BOM count.

FAQ
What is the function of the dual VD pins on the UPD16879GS-BGG-A?
The UPD16879GS-BGG-A features two VD pins (pins 31 and 32) to accept video sync signals for frame-synchronized motor stepping. Only one VD pin should be used - the other must be tied to VDD (if VD is used) or GND (if unused) per datasheet Note 2. This ensures precise timing alignment between image capture and lens motion, critical for jitter-free zoom and focus in camcorders.
How does the UPD16879GS-BGG-A achieve 64-step microstepping without external components?
The UPD16879GS-BGG-A achieves 64-step microstepping through an integrated current-controlled architecture that digitally modulates H-bridge conduction based on serially programmed EVR voltage (50–250 mV) and internal reference. Table 2 in the datasheet shows exact phase current ratios per step; no external DAC, chopper IC, or microstepping indexer is required - all logic resides on-die.
Can the UPD16879GS-BGG-A drive unipolar stepper motors?
No, the UPD16879GS-BGG-A is designed exclusively for bipolar stepper motors. Its four H-bridges (A1/A2, B1/B2, C1/C2, D1/D2) deliver bidirectional current per winding, matching standard 4-wire bipolar configurations. Unipolar motors (5- or 6-wire) require center-tapped windings and single-direction drive - incompatible with this IC's topology and current-sense architecture.
What is the purpose of the FILx pins (FILA–FILD) on the UPD16879GS-BGG-A?
The FILA–FILD pins on the UPD16879GS-BGG-A connect external 1000 pF filter capacitors to suppress high-frequency noise on the current-sense feedback path. Each pair (e.g., FILA/FILB for α1/α2) stabilizes the internal current regulation loop, preventing oscillation during PWM chopping - essential for maintaining accurate 64-step microstepping performance under dynamic load.
Does the UPD16879GS-BGG-A support stall detection or thermal shutdown?
The UPD16879GS-BGG-A does not include integrated stall detection or thermal shutdown circuitry. Protection relies on external design: current-limiting via FBA/FBB/FBC/FBD sense resistors (6.8 Ω), board-level thermal management (PT ≤ 1.0 W), and system-level monitoring using EXTα/EXTβ outputs or EXP0/EXP1 status flags. Safe operation requires adherence to absolute max ratings - especially TCH(MAX) = 150°C and IM(pulse) ≤ ±0.3 A/ch.
