PIC16HV753-E/P Descripción general
A microcontroller (MCU) is a single-chip computer that integrates a CPU, memory (Flash/RAM), and programmable peripherals. The PIC16HV753 belongs to the PIC16F family of 8-bit RISC microcontrollers, which sit in the broader hierarchy of embedded microcontrollers -> microprocessors -> semiconductors. The 8-bit RISC Harvard architecture executes most instructions in a single clock cycle, simplifying deterministic timing for control applications.
Key features include 12 ADC channels with 10-bit resolution, four hardware PWM outputs, a 9-bit DAC, two comparators, a high-voltage shunt regulator for direct connection to 12V battery rails, and Enhanced Mid-Range Core with 49 instructions plus 16-level hardware stack. The integrated HV shunt eliminates the need for external regulation when powered from unregulated DC sources.
The PIC16HV753-E/P uses an Enhanced Mid-Range 8-bit core built on Microchip's proprietary process, supporting in-circuit serial programming (ICSP) via two pins and self-programmable Flash for bootloader-style firmware updates. The HV shunt regulator provides a regulated 3.3V or 5V supply to internal logic, enabling direct connection to 12V lead-acid or similar unregulated rails without an external LDO.
Typical applications include battery charging controllers, LED drivers, DC-DC converters, 12V industrial sensors, and consumer appliance controls where the high-voltage shunt simplifies the power tree and reduces external components.
When designing with this part, configure the MCLR pin as input by tying it through a resistor to VDD to avoid unintentional resets in noisy environments, and provide adequate decoupling (100nF) close to the VDD pin.

Aplicaciones típicas
PIC16HV753-E/P es adecuado para 6 aplicacións: 12V Battery Charging Controller, LED Lighting Driver with Dimming, DC-DC Converter Control, 12V Industrial Sensor Interface, Consumer Appliance Control Board, Automotive 12V Accessory Module.
12V Battery Charging Controller
The PIC16HV753-E/P is ideal for 12V lead-acid battery charging controllers because its integrated high-voltage shunt regulator accepts the unregulated battery rail directly without an external LDO. The 12-channel 10-bit ADC monitors battery voltage and current with sufficient resolution for CC/CV charge profiling, while 4 PWM channels drive a synchronous buck converter MOSFET bridge at typical switching frequencies of 20-100 kHz. The HV shunt draws only a few milliamps during regulation, keeping quiescent losses low. Engineers should size the input Zener for transient protection above 13.5V and use the 9-bit DAC to set programmable current thresholds for multi-stage charging. This same-brand PIC16 architecture shares development tools with the broader PIC16F family.
Recomendado
LED Lighting Driver with Dimming
The PIC16HV753-E/P drives high-brightness LED strings in architectural and automotive lighting thanks to its 4 hardware PWM outputs that provide independent dimming channels for RGBW color mixing or multi-zone lighting control. The integrated HV shunt connects directly to 12V or 24V LED driver rails without external regulation, while the 9-bit DAC sets constant-current reference levels for closed-loop brightness feedback. The 20 MHz CPU executes color-space conversion and thermal compensation algorithms in real time. Choose this part when you need multi-channel PWM dimming with HV supply capability; for simple single-string LEDs the PIC12HV752 may suffice.
Recomendado
DC-DC Converter Control
The PIC16HV753-E/P serves as a digital controller for isolated and non-isolated DC-DC converters, leveraging its 4 PWM channels to drive synchronous MOSFET bridges in buck, boost, or push-pull topologies. The 12-channel 10-bit ADC samples input/output voltage and inductor current at the switching frequency for peak-current-mode control, while the integrated HV shunt regulates supply from 12-24V rails typically used in industrial distributed power. The 3.5KB Flash holds firmware for soft-start, overcurrent protection, and efficiency optimization algorithms. This same-brand PIC16 controller is drop-in compatible with PIC16HV753 industrial and extended temperature variants.
Recomendado
12V Industrial Sensor Interface
The PIC16HV753-E/P interfaces directly with 12V or 24V industrial sensors because its integrated HV shunt regulator eliminates the need for an external LDO between the field wiring and the MCU. The 12-channel 10-bit ADC reads multiple sensor inputs simultaneously - temperature, pressure, flow, or 4-20mA current loops - while 2 comparators provide hardware threshold detection for alarm outputs. The 128B RAM and 3.5KB Flash support Modbus RTU or custom protocols over UART. Engineers should add TVS diodes for surge protection on the HV supply pin. This same-brand PIC16 architecture integrates cleanly with Microchip's free MPLAB X IDE and XC8 compiler toolchain.
Recomendado
Consumer Appliance Control Board
The PIC16HV753-E/P is well-suited for consumer appliance control boards (washing machines, dishwashers, microwave ovens) because its HV shunt regulator accepts the rectified mains-derived 12V rail directly, eliminating a separate regulator stage. The 4 PWM outputs drive motor speed control via TRIAC or IGBT interfaces, while the 9-bit DAC provides reference voltages for analog sensor calibration. The 14-pin PDIP package enables hand-solderable prototyping and through-hole manufacturing for low-volume appliance production. For surface-mount cost optimization in high-volume consumer products, the SOIC-14 PIC16HV753-E/SL variant offers identical electrical performance.
Recomendado
Automotive 12V Accessory Module
The PIC16HV753-E/P powers 12V automotive accessory modules such as auxiliary lighting controllers, seat heaters, or sensor interfaces because its integrated HV shunt regulator handles automotive battery transients directly. The 12-channel 10-bit ADC monitors battery voltage for low-voltage disconnect protection, while the 4 PWM channels drive MOSFET outputs for heating elements or fan motors. The -40C to +125C operating temperature range covers automotive underhood and cabin environments. For AEC-Q100 qualified designs, consider PIC16F18313 or PIC16F1614 in automotive-grade variants; the PIC16HV753 is industrial-grade but commonly used in non-safety automotive accessories.

Notas de diseño
The PIC16HV753-E/P's integrated HV shunt regulator accepts up to 13.5V input but requires a series current-limiting resistor between the input supply and the HVIN pin. Calculate R based on worst-case input voltage and desired shunt current: R = (Vin_max - 5V) / I_shunt. A 1kohm resistor at 12V input yields approximately 7mA shunt current. Add a Zener diode (e.g., 15V) on HVIN for transient protection above the regulator's maximum input rating. Decouple VDD with 100nF ceramic placed within 5mm of the pin.
The MCLR pin (pin 4) on the PIC16HV753-E/P must NOT be left floating - this causes intermittent resets in electrically noisy environments. Tie MCLR to VDD through a 10kohm resistor, or to a supervisor circuit for production designs. Additionally, the OSC1/OSC2 pins must be configured correctly for the chosen clock source - leaving them unconfigured while expecting internal oscillator operation will prevent the MCU from starting. Review CONFIG1 register settings in code before first programming.
When routing the 14-pin PDIP PCB layout, keep the analog inputs (AN0-AN7) physically separated from PWM outputs and switching nodes to minimize crosstalk. Place the VDD decoupling capacitor within 5mm of the VDD pin and use a ground plane on the bottom layer for return currents. For HV shunt applications, route the HVIN trace away from sensitive analog signals to avoid injecting noise from the shunt regulator switching. The ICSP programming pins (RA0/ICSPDAT, RA1/ICSPCLK) should be accessible on the PCB for in-field firmware updates.
