Product details
Overview
MTCH650T-I/MV from Microchip Technology is a 21-channel high-voltage level shifter IC with serial SPI interface and independent output enable (OE), operating from 1.8V to 5.5V input and supporting external VPPIN up to 18V. It delivers up to 100 mA total output current (5 mA per channel), features <200 µA quiescent current, and targets HV display bias, capacitive touch driver, and segmented LCD/EL panel control.
For engineers reviewing the MTCH650T-I/MV datasheet, MTCH650T-I/MV pinout, MTCH650T-I/MV application, or MTCH650T-I/MV equivalent, key selection criteria include its 21 HV analog outputs, OE-independent latching, 1 MHz SPI interface, external boost voltage compatibility, and SOIC/UQFN package options - all critical for low-power, high-channel-count HV switching in space-constrained industrial and consumer displays.
Technical Context
The MTCH650T-I/MV functions as a programmable HV line driver without integrated boost circuitry - it requires an external high-voltage source connected to VPPIN (3.6–18V). Its 21 OUTxx pins are digitally controlled via a 24-bit serial interface (3-byte DATA word) and configured using a dedicated CONFIG word that sets shutdown state and soft-start behavior, though voltage/current regulation is handled externally.
Operation relies on three core digital inputs: OE (asynchronous output enable), LE (active-low latch enable), and standard SPI CLK/DIN signals. All 21 HV outputs are level-shifted analog drivers referenced to VPPIN, with each capable of sourcing up to 5 mA while maintaining rail-to-rail logic-controlled states - enabling precise per-channel HV activation in multiplexed display architectures.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 1.8V to 5.5V - powers internal logic and level shifters; decoupling with ≥1 µF capacitor required at VDD. |
| VPPIN Range | 3.6V to 18V - external HV supply input; defines maximum output voltage swing across all 21 channels. |
| Output Channels | 21 HV analog outputs (OUT00–OUT20) - each independently controllable via 21-bit DATA register. |
| Max Output Current | 100 mA total (5 mA per channel) - limits simultaneous active channel count under full load conditions. |
| Quiescent Current | <200 µA - enables battery-powered operation with minimal standby power draw. |
| SPI Interface Speed | Up to 1 MHz - supports fast configuration updates without requiring high-speed MCU peripherals. |
| Shutdown Current | 1.5 µA typical - ensures ultra-low power retention during system sleep modes. |
Pinout & Package
MTCH650T-I/MV is available in 28-pin SOIC and 28-pin UQFN (4×4 mm) packages. Both variants share identical pin functionality and I/O mapping per Microchip DS40001749A.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VSS | Ground reference | Electrical return path for all internal circuits and HV outputs; must be low-impedance. |
| VDD | Logic supply input | Powers internal registers, SPI interface, and level-shifting circuitry; requires ≥1 µF decoupling. |
| VPPIN | External HV supply input | Provides high-voltage rail to all 21 OUTxx pins; accepts 3.6–18V; decoupling ≥1 µF mandatory. |
| OE | Asynchronous output enable | Drives all OUTxx to GND when low; enables configured outputs when high; overrides SPI timing. |
| LE | Latch enable (active-low) | Transfers serial data from shift register into output latches on rising edge; acts as chip-select when held high. |
| CLK | SPI clock input | Falling-edge sampled; synchronizes DIN data loading; max 1 MHz frequency supported. |
| DIN | SPI data input | Serial 24-bit stream: LSB = 0 selects CONFIG word, LSB = 1 selects DATA word. |
| OUT00–OUT20 | HV analog outputs | 21 individually controllable level-shifted outputs; each sources up to 5 mA when enabled by OE and DATA register. |
Key Features
| Feature | Design Value |
|---|---|
| 21-channel HV level shifting | Enables direct drive of 21 independent high-voltage nodes (e.g., EL panel segments or LCD backplanes) from low-voltage MCU logic. |
| Independent OE control | Allows instantaneous global on/off of all HV outputs without retransmitting SPI data - critical for flicker-free display blanking. |
| 24-bit serial interface | Supports both configuration (CONFIG) and output mask (DATA) loading over same 3-wire SPI bus, minimizing MCU pin count. |
| Low-power operation | Sub-200 µA quiescent and 1.5 µA shutdown currents enable integration into energy-sensitive portable and IoT display systems. |
| SOIC/UQFN dual packaging | Offers design flexibility: SOIC for prototyping and repairability; UQFN (4×4 mm) for compact, high-density PCB layouts. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar HV level shifter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MTCH652T-I/MV | Integrated boost converter (19-channel), no VPPIN; uses OSCIN/PWM and LC pins; lower channel count. | Self-contained HV generation eliminates external supply but lacks MTCH650T-I/MV's 21-channel flexibility and external VPPIN range. | Select MTCH652T-I/MV only if board space constraints prohibit external boost and 19 channels suffice. |
| TPS65136RGTR | Dual-output HV DC-DC controller (±15V), no integrated level shifters; requires external FETs and gate drivers. | Designed for TFT-LCD source/gate drivers, not discrete HV line driving; lacks serial interface and per-channel control. | Choose TPS65136RGTR when generating symmetric bipolar HV rails is required, not for 21-channel unidirectional level shifting. |
Compared with MTCH652T-I/MV, MTCH650T-I/MV provides two additional HV outputs and full external VPPIN flexibility at the cost of requiring an external boost stage; versus TPS65136RGTR, it delivers integrated digital control and per-pin latching - making MTCH650T-I/MV uniquely suited for applications demanding high channel count, low-power, and MCU-driven HV sequencing.

FAQ
What is the function of the VPPIN pin on the MTCH650T-I/MV?
The VPPIN pin on the MTCH650T-I/MV serves as the external high-voltage supply input, accepting 3.6V to 18V to power all 21 HV output channels. Unlike the MTCH652, the MTCH650T-I/MV does not include an internal boost circuit - VPPIN must be driven by an external HV source such as a DC-DC converter or another MTCH652 device. A minimum 1 µF decoupling capacitor is required between VPPIN and VSS.
How many output channels does the MTCH650T-I/MV support, and what is the per-channel current limit?
The MTCH650T-I/MV supports 21 high-voltage output channels (OUT00 through OUT20), each capable of sourcing up to 5 mA. The total output current is rated at 100 mA, meaning up to 20 channels may be fully active simultaneously under worst-case conditions. This per-channel rating ensures stable operation across diverse display and sensor biasing loads without thermal derating in standard SOIC or UQFN packages.
Does the MTCH650T-I/MV include an integrated boost converter?
No, the MTCH650T-I/MV does not include an integrated boost converter. It is a pure HV level shifter and line driver that requires an external high-voltage supply connected to the VPPIN pin. In contrast, the MTCH652T-I/MV integrates a boost circuit with PWM input (OSCIN) and inductor connection (LC). The MTCH650T-I/MV's architecture allows greater flexibility in HV source selection, higher output voltage range (up to 18V), and 21-channel capability - making it ideal when external boost control or higher channel density is needed.
What is the role of the OE (Output Enable) pin on the MTCH650T-I/MV?
The OE (Output Enable) pin on the MTCH650T-I/MV provides asynchronous, hardware-level control over all 21 HV outputs. When OE is logic low, all OUTxx pins are actively driven to VSS (GND); when OE is logic high, outputs reflect the states set in the DATA register. Critically, OE operates independently of the SPI interface and latch enable (LE), enabling instant global blanking or safety shutdown - essential for flicker-free display updates and fail-safe system behavior in industrial HMIs and medical devices.
Which package options are available for the MTCH650T-I/MV, and how do they differ electrically?
The MTCH650T-I/MV is offered in two RoHS-compliant packages: 28-pin SOIC (wide-body) and 28-pin UQFN (4×4 mm, 0.5 mm pitch). Electrically, both packages share identical pinout, absolute maximum ratings, and functional specifications - including 1.8–5.5V VDD operation, 3.6–18V VPPIN support, and 21-channel HV output capability. The UQFN variant offers superior thermal performance (2W vs. 1.4W SOIC at 25°C ambient) and reduced PCB footprint, while the SOIC version simplifies prototyping, rework, and automated optical inspection.
