PIC16HV753-E/ML Visão geral
What is a PIC16 Mid-Range microcontroller? The PIC16 mid-range family is a category of 8-bit RISC microcontrollers from Microchip Technology using a 14-bit instruction set. It occupies the middle tier of Microchip's PIC microcontroller portfolio - above the baseline PIC10/12/14/16 baseline (12-bit) and below the PIC18 enhanced (16-bit) architecture - and is widely used in cost-sensitive embedded designs where deterministic timing, low power, and integrated analog peripherals matter more than raw throughput.
Key features of the PIC16HV753-E/ML include an internal 8MHz oscillator (with PLL), one op-amp, two high-speed analog comparators with 50ns propagation delay, one Capture/Compare/PWM (CCP) module, eight 10-bit ADC channels with internal voltage reference, and a 9-bit DAC. The 'HV' in the part number designates the integrated high-voltage shunt regulator that allows operation directly from a high-voltage rail, eliminating the need for an external low-dropout regulator.
The device is built on CMOS technology and uses the standard PIC mid-range core. Its 35 instruction set with 200ns instruction cycle at 20MHz yields predictable, deterministic timing for motor control and power-supply loop tasks. The 16-QFN EP package includes an exposed thermal pad that must be soldered to the PCB ground plane to meet the datasheet's thermal specifications.
Typical applications include LED lighting drivers, battery chargers, smart battery packs, power-supply primary-side controllers, motor-control signal conditioning, and industrial sensor transmitters. The 'HV' shunt regulator allows the MCU to be powered from a 2V to a much higher DC bus after a current-limiting resistor, simplifying isolated and non-isolated SMPS designs.
When designing with this part, ensure the exposed pad on the QFN package is soldered to a sufficient copper pour (typically 1 square inch of 2oz copper) to keep junction temperature within safe limits. Verify that the high-voltage shunt regulator's input current limit resistor is sized for worst-case VIN, since excessive dissipation in this resistor can exceed package ratings.

Aplicações típicas
PIC16HV753-E/ML é adequado para 6 aplicaçãos: LED Lighting Drivers, Smart Battery Pack Controllers, Isolated AC-DC Power Supply Primary-Side Controller, Industrial Sensor Transmitters, Motor Control Signal Conditioning, Capacitive Touch User Interfaces.
LED Lighting Drivers
The PIC16HV753-E/ML is well-suited to primary-side controlled LED driver topologies where the MCU must operate directly from a rectified mains-derived high-voltage DC bus. The integrated high-voltage shunt regulator accepts the bus voltage through a single series current-limiting resistor, eliminating the need for a separate low-dropout regulator and reducing BOM cost by 5-10 cents per node. The 9-bit DAC and 8-channel 10-bit ADC let the firmware close current and color-mixing loops in real time, while the 20MHz CPU provides ample bandwidth for PWM dimming above 1kHz to avoid visible flicker. The op-amp and 50ns comparators handle zero-current-detection and valley switching for quasi-resonant flyback topologies common in commercial LED fixtures.
Recomendado
Smart Battery Pack Controllers
Inside a smart lithium-ion or NiMH battery pack, the PIC16HV753-E/ML can monitor cell voltage, current, and temperature while communicating over SMBus or single-wire protocols. The integrated HV shunt regulator allows the pack to draw a small housekeeping current from a multi-cell stack (4-6 cells in series) without a separate regulator IC, simplifying the protection circuit module. The 8-channel ADC samples each cell voltage with 10-bit resolution (LSB around 4.9mV at 5V reference), sufficient for accurate state-of-charge estimation, and the op-amp can be configured as a transimpedance amplifier for current sensing across a sense resistor. The 16-QFN package keeps the PCB small enough to fit inside 18650 and 21700 form factors.
Recomendado
Isolated AC-DC Power Supply Primary-Side Controller
For isolated AC-DC adapters up to 5W, the PIC16HV753-E/ML acts as the primary-side controller in flyback or buck topologies, drawing power directly from the rectified 400V DC bus through the HV shunt regulator. The 20MHz CPU executes current-mode control loops at 50-100kHz with deterministic timing, while the high-speed 50ns comparators detect peak current and demagnetization events. The CCP module generates the primary-side PWM, and the 9-bit DAC programs the reference for current limit. This approach removes the auxiliary winding regulator typically required for primary-side ICs, reducing standby power to under 100mW and BOM count by 1-2 components per power supply.
Recomendado
Industrial Sensor Transmitters
4-20mA loop-powered and two-wire industrial sensor transmitters benefit from the PIC16HV753-E/ML's ability to operate from the loop current itself. The HV shunt regulator drops the loop voltage (typically 12-30V) to the internal 5V rail with only one external resistor, while the 10-bit ADC digitizes bridge sensor, RTD, or thermocouple signals with adequate resolution for process control. The op-amp handles signal conditioning for strain-gauge bridges, and the comparators provide fast over-range detection. The -40C to +125C extended temperature range allows deployment in harsh factory environments near motors and heaters.
Recomendado
Motor Control Signal Conditioning
Small brushed DC and stepper motor control signal-conditioning tasks fit naturally on the PIC16HV753-E/ML. The 20MHz core runs trapezoidal commutation at 30kHz, the CCP module outputs direction and step pulses, and the op-amp amplifies shunt-resistor current sense for closed-loop torque control. The high-speed 50ns comparators implement cycle-by-cycle overcurrent protection, while the 9-bit DAC programs reference levels for current limit. The HV shunt regulator eliminates the external 5V regulator needed in 24V motor systems, simplifying PCB layout and reducing quiescent current.
Recomendado
Capacitive Touch User Interfaces
The PIC16HV753-E/ML's 8-channel ADC with internal voltage reference, combined with the op-amp and 50ns comparators, supports capacitive touch sensing via the mTouch software framework from Microchip. Up to 8 touch buttons or a small slider can be implemented using charge-time-measurement techniques, with the 20MHz CPU providing fast response (<10ms) for responsive UI feedback. The HV shunt regulator allows direct connection to industrial 24V rails, making the MCU ideal for white goods, appliance control panels, and industrial HMI keypads that operate from 12-24V DC.

Notas de projeto
The 16-QFN (4x4) package's exposed thermal pad (EP) MUST be soldered to a PCB ground plane. Estimated: with 1 square inch of 2oz copper on a 4-layer FR-4 board, theta_JA drops to roughly 35-45 C/W versus 70+ C/W with no copper. For high-voltage shunt regulator applications dissipating more than 200mW internally, additional copper area or thermal vias under the EP are required to keep the junction below 150C at 125C ambient.
The HV shunt regulator requires an external series current-limiting resistor between the high-voltage bus and the HVIN pin. Estimated: for a 24V industrial bus, a 2.7k ohm resistor limits inrush to about 9mA. Verify worst-case power dissipation in this resistor: at 24V input and 5mA quiescent, the resistor dissipates ~120mW - select at least a 1/4W (250mW) part with 50% derating. Decouple VDD with a 0.1uF ceramic capacitor placed within 5mm of the VDD pin.
Route the analog signals (AN0-AN11, OPA1IN+, OPA1IN-) away from digital switching traces and the high-voltage shunt regulator input trace. Keep the analog ground (VSS) connection short and direct to the exposed pad. Place the 0.1uF VDD bypass capacitor as close as possible to pin 4 (VDD) and the HVIN series resistor within 3mm of pin 5 to minimize parasitic inductance on the high-voltage path.
Do not confuse PIC16HV753-E/ML with PIC16F753-E/ML: the HV part has an integrated high-voltage shunt regulator on pin 5 (HVIN), while the F version uses pin 5 for a regular I/O. Substituting F753 in an HV753 socket leaves the MCU unpowered on a high-voltage bus. Also note the ML suffix (16-QFN 4x4) is not interchangeable with the SO (SOIC-16) or SP (PDIP-16) packages - the pinout and footprint differ.
