L9110S-MS Overview
The MSKSEMI L9110S-MS is a highly integrated single-channel brushed DC (BDC) motor driver IC built around a full all-NMOS H-bridge with an internal charge pump circuit that generates the necessary gate drive voltage, eliminating the need for an external bootstrap supply or P-channel high-side FETs. Operating from 2.5V to 12V, the device covers single-cell Li-ion, 2S Li-ion, and standard AA/AAA battery pack supply rails in a single SOP-8 package, making it well suited to compact consumer and toy motor drive designs. The L9110S-MS supports four distinct motor control states — forward rotation, reverse rotation, stop, and active brake — controlled directly via its PWM INA/INB input interface.
The L9110S-MS delivers a 1.2A continuous output current and a 2A peak current with a combined high-side and low-side RDS(on) of 450mΩ, keeping conduction losses and device self-heating low across its operating range. A standby current of just 100nA (typical 0.1µA at 6V) is one of the lowest figures in the SOP-8 brushed motor driver category, making the L9110S-MS particularly well matched to coin-cell or single-AA battery applications where idle power consumption directly determines product shelf life. Operating quiescent current is a similarly low 200µA typical, contributing to overall system efficiency during active but light-load operation.
Integrated protection features in the MSKSEMI L9110S-MS include over-temperature shutdown and under-voltage lockout (UVLO), both of which protect the device and connected motor under fault or low-battery conditions without requiring any external protection components. The compact SOP-8 footprint and minimal external component count make the L9110S-MS straightforward to drop into space-constrained PCB designs for volume consumer production.

Applications
The MSKSEMI L9110S-MS is ideally suited to compact, battery-powered products requiring low-voltage brushed DC motor control with minimal board footprint and ultra-low standby drain. Primary application areas include RC toys and robotic kits, motorised camera pan/tilt mechanisms, portable fan and ventilation modules, handheld personal care appliances, and compact vending or dispensing mechanisms. Its 100nA standby current and 2.5V minimum supply also make it an excellent fit for coin-cell powered IoT sensor actuators and single-AA battery consumer gadgets where maximising battery runtime in both active and idle states is a key product requirement.
Pin-to-Pin Compatible Alternatives
Specifying a pin-to-pin compatible replacement such as the L9110S-MS enables procurement and design teams to cut unit BOM cost and diversify their supply chain without any PCB layout revision or firmware modification.
| Reference Part Number | Original Manufacturer | Why Choose L9110S-MS |
|---|---|---|
| DRV8837C | Texas Instruments | Pin-to-pin SOP-8 compatible replacement; MSKSEMI L9110S-MS offers equivalent PWM H-bridge function at a lower unit cost with flexible UK MOQ through ABL Semi |
| TC78H621FNG | Toshiba | Direct footprint-compatible alternative; L9110S-MS delivers a lower standby current (100nA vs 200nA typical) for improved battery shelf life in always-on designs |
| BD6211F-E2 | ROHM Semiconductor | Compatible low-voltage BDC H-bridge function in the same SOP-8 package; L9110S-MS provides an ultra-low 100nA Iq not matched by the BD6211F in standby mode |
| MX1508 | MIXIC | Factory-authenticated MSKSEMI supply through ABL Semi ensures full component traceability and compliance-friendly UK trade documentation unavailable through grey-market MX1508 channels |
Frequently Asked Questions
Is L9110S-MS RoHS compliant?
Yes. The MSKSEMI L9110S-MS is manufactured in full compliance with the RoHS Directive (2011/65/EU), restricting hazardous substances including lead, cadmium, and mercury. Compliance documentation is available upon request through ABL Semi.
What are the pin-to-pin replacements for L9110S-MS?
The L9110S-MS is a pin-to-pin compatible replacement for widely used low-voltage brushed DC motor drivers including the TI DRV8837C, Toshiba TC78H621FNG, and ROHM BD6211F in the same SOP-8 footprint. Please refer to the compatibility table above for a full advantage comparison for each substitution.
What is the minimum order quantity (MOQ) for L9110S-MS?
ABL Semi offers flexible MOQ for L9110S-MS, supporting both prototype quantities and mass production orders. Contact us for current stock and pricing.
What package options are available for L9110S-MS?
The MSKSEMI L9110S-MS is available in the standard SOP-8 package, a widely adopted 8-pin small-outline format fully compatible with conventional SMT reflow assembly. Contact ABL Semi to confirm current stock availability and lead times.
Does the L9110S-MS support PWM speed control, and what logic voltage levels are compatible?
Yes. The L9110S-MS features a PWM INA/INB input interface that accepts PWM signals directly from a host microcontroller, with motor speed proportional to the applied duty cycle. The input logic thresholds are compatible with both 3.3V and 5V MCU GPIO and PWM output pins across the device’s 2.5V–12V supply range, requiring no external level-shifting components. Forward speed, reverse speed, active brake, and coast (stop) operating modes are all selectable through INA and INB pin state combinations, giving the designer full bidirectional speed and braking control from a standard two-pin MCU PWM output pair.
