PIC16HV753-I/SL Overview
A PIC microcontroller is a compact, low-power embedded controller that combines a CPU core, non-volatile flash memory for program storage, volatile RAM for data, and a rich mix of peripherals (ADC, timers, PWM, comparators, communication ports) on a single die. Within the broader taxonomy, the PIC16HV753 belongs to the PIC16F/HV family of mid-range 8-bit microcontrollers, itself a subcategory of embedded microcontrollers, which fall under integrated circuits for power management and control. The mid-range PIC16 core uses a 14-bit instruction word optimized for deterministic, single-cycle execution.
Key features of the PIC16HV753 include 35 KB of total flash (using the same flash cell as the F-variant, of which 3.5 KB is available to user code), an internal 8 MHz high-precision oscillator, hardware 9-bit DAC, multiple 10-bit PWM modules, configurable logic cells, and on-chip comparators. The internal shunt regulator eliminates the need for an external 5V LDO in many high-voltage applications, simplifying the BOM. The industrial temperature grade (-40C to +85C) makes the part suitable for harsh-environment deployments.
In circuit terms, the HV753 integrates its own high-voltage regulator so that downstream analog and digital blocks operate from a clean, internally regulated rail regardless of upstream supply variation between 2V and the user-set VDDIO. The 9-bit DAC and op-amp peripherals support analog signal generation and conditioning without external components.
Typical applications include LED lighting controllers with analog dimming, battery chargers for portable systems, intelligent battery management, power-conversion feedback loops, and consumer/industrial control nodes. The wide operating voltage and integrated regulator cut part count versus discrete MCU + LDO designs.
When designing with the PIC16HV753, ensure the shunt regulator current limit is configured correctly using the internal resistor divider and that decoupling SL holds at 100 nF plus 10 uF bulk placed within 5 mm of VDD.

Typical Applications
PIC16HV753-I/SL is suitable for 6 applications: LED Lighting Driver with Analog Dimming, Battery Charger Controller, Intelligent Power Management Node, Motor Speed Control (Small DC/BLDC), Sensor Signal Conditioning, Consumer Remote Control / User Interface.
LED Lighting Driver with Analog Dimming
The PIC16HV753's integrated high-voltage shunt regulator enables direct connection to a 12V or 24V LED string supply without an external LDO, simplifying the BOM. Its 9-bit DAC supports analog dimming curves from 0% to 100% brightness with sub-1% steps, while the PWM modules provide flicker-free dimming for high-frequency LED drivers. The 20 MHz core is fast enough for closed-loop current regulation at 1 kHz+ bandwidth, and the 3.5 KB flash comfortably fits state-machine lighting protocols such as DALI or 0-10V analog dimming.
Recommended
Battery Charger Controller
The PIC16HV753 is well-suited for single-cell Li-Ion and NiMH charger topologies because its internal shunt regulator tolerates a wide input voltage range typical of USB, solar, or wall-adapter sources. The 9-bit DAC sets the constant-current/constant-voltage (CCCV) charge profile, while the comparators detect battery presence and end-of-charge voltage with no external analog ICs. The 128-byte RAM easily handles state-machine charging profiles, and the 14-SOIC package fits inside compact charger bricks. Industrial temperature grade ensures reliability in warm charger enclosures.
Recommended
Intelligent Power Management Node
The PIC16HV753's HV shunt regulator makes it ideal for slave nodes on a high-voltage DC bus (e.g., 24V industrial or 48V telecom rails). The MCU can directly sense and modulate that rail without a separate regulator, while the internal ADC and comparators monitor current and voltage faults. Its 3.5 KB flash supports firmware implementing PMBus-lite or custom serial protocols over UART, and its 20 MHz throughput handles real-time control loops. The 14-SOIC footprint simplifies integration on standard 2-layer industrial PCBs.
Recommended
Motor Speed Control (Small DC/BLDC)
For small brushed DC or sensorless BLDC motor control up to several hundred mA, the PIC16HV753 provides 10-bit PWM, hardware comparators for back-EMF sensing, and the HV regulator for direct bus connection. The 5 MIPS throughput handles trapezoidal commutation at up to 50,000 RPM at low pole counts, while the 9-bit DAC can synthesize reference-speed setpoints. The 14-SOIC package suits small-motor PCBs used in fans, pumps, and small appliances, with industrial temperature grade handling motor self-heating.
Recommended
Sensor Signal Conditioning
The PIC16HV753's integrated 9-bit DAC, op-amp, and comparators enable direct interfacing with bridge sensors (load cells, pressure transducers) without external analog front-end ICs. The internal 8 MHz high-precision oscillator provides a stable excitation source, and the PIC16 core runs calibration routines to linearize sensor output. Its HV regulator allows operation from industrial 24V transducer rails. The 3.5 KB flash stores calibration coefficients and linearization tables for sensor-specific compensation.
Recommended
Consumer Remote Control / User Interface
The PIC16HV753 fits battery-powered remote controls and HMI panels thanks to its low-power PIC16 mid-range core, the ability to wake on comparator interrupts, and the HV regulator option for line-powered HMI boards. The 3.5 KB flash supports IR protocol libraries (RC5, NEC, SIRC), and the PWM outputs drive LED feedback indicators without external drivers. Its 14-SOIC package is well suited to slim consumer enclosures, and industrial temperature grade ensures reliability in outdoor or garage environments.

- QFN package variant for compact designs (vs PIC16HV753-I/P)
Design Notes
The HV753's internal shunt regulator requires careful configuration: the regulator current must be set via the dedicated SHUNT pin resistor to limit power dissipation. For a 24V rail input, use at least a 4.7 kohm resistor on SHUNT to keep internal dissipation under 250 mW. Add a bulk capacitor (>=10 uF) on VDD within 5 mm of the pin. Place a 100 nF decoupling capacitor adjacent to VDD per the manufacturer datasheet reference schematic.
Estimated: at 24V input and 20 mA shunt regulator current, internal dissipation is approximately 0.48 W. The 14-SOIC package has a theta_JA around 70 C/W on a 1-square-inch copper pour, yielding a junction temperature rise of roughly 33 C above ambient. For continuous operation near the maximum industrial temperature (85C), ensure PCB copper area provides adequate heatsinking or derate input voltage accordingly.
Keep the ICSP programming traces (RA0/RA1) short and routed away from high-current traces to avoid programming glitches. The 14-SOIC land pattern should use 0.6 mm pitch with thermal pads connected to VSS plane. Place the shunt resistor close to the SHUNT pin to minimize parasitic inductance. Per Microchip AN1030 routing guidelines, isolate analog inputs with a guard trace if used with low-impedance sources.
Critical: do not exceed the absolute maximum HV input voltage rating per the datasheet; over-voltage can permanently damage the shunt regulator. Ensure the MCLR pin (RA3) is not left floating; tie to VDD via 10 kohm pull-up per Microchip guidance. Verify the PIC16F753 vs HV753 BOM change when sourcing alternatives, since the F-variant lacks the internal regulator and may cause silent failure if substituted without external LDO redesign.
The 9-bit DAC output (DACCON/VCAP pin) requires a low-ESR decoupling capacitor (1 uF ceramic minimum) close to the pin to ensure monotonic output transitions. For applications driving ADC inputs from the same chip, separate analog and digital supply decoupling with ferrite beads to minimize digital switching noise coupling. Use the configurable logic cell (CLC) peripherals carefully - their asynchronous paths can introduce glitches if not synchronized to the system clock.
