Product details

Overview

NCV8502PDW100R2G from onsemi is a 10 V, ±2.0% accuracy automotive-grade LDO linear regulator delivering 150 mA output current with 600 mV max dropout at full load, 90 µA quiescent current at light load, and integrated active RESET (functional down to 1.0 V output), FLAG monitor, and DELAY timing-designed for battery-powered microprocessor systems in harsh automotive environments.

For engineers reviewing the NCV8502PDW100R2G datasheet, pinout, applications, or equivalent options, key selection criteria include its AEC-Q100 qualification, 60 V peak transient tolerance, −15 V reverse voltage protection, exposed-pad SOIC-16 thermal performance (R_JA = 56 °C/W), and dual-voltage monitoring (RESET + FLAG) for safe microprocessor shutdown sequencing.

Technical Context

The NCV8502PDW100R2G implements a bandgap-referenced error amplifier with current-limit and thermal shutdown protection, supporting fixed 10 V output without external feedback. Its RESET circuit uses hysteresis (0.97×/0.98× V_OUT) and operates independently of regulation status, remaining valid even when V_OUT drops to 1.0 V.

The FLAG monitor compares MON pin voltage against a 1.20 V internal reference (±0.11 V hysteresis); when configured via external resistor divider, it provides early warning before RESET assertion. DELAY timing is set by an external capacitor charged at 2.5 µA, enabling programmable reset delay (e.g., 23.8 ms with 33 nF).

Key Specifications

Parameter	Value and Actual Design Meaning
Output Voltage	Fixed 10.0 V ±2.0% - ensures stable supply for 10 V logic or analog subsystems without external resistors.
Max Output Current	150 mA - sufficient to power microcontrollers, CAN transceivers, or sensor interfaces in automotive ECUs.
Dropout Voltage	600 mV @ 150 mA - enables operation with input as low as 10.6 V while maintaining regulation under cold-crank conditions.
Quiescent Current	90 µA @ 100 µA load - minimizes battery drain during sleep modes in always-on vehicle modules.
RESET Threshold	9.20 V (low) to 9.40 V (high) - triggers reset before V_OUT falls below functional margin for 10 V systems.
Transient Tolerance	+60 V peak (load dump), −15 V reverse - meets ISO 7637-2 Pulse 5a/b and reverse-battery requirements.
Operating Temp	−40 °C to +150 °C junction - qualified for under-hood automotive placement per AEC-Q100 Grade 1.

Pinout & Package

NCV8502PDW100R2G uses the SOIC-16 wide-body package with exposed thermal pad (Case 751AG), offering 56 °C/W junction-to-ambient thermal resistance and optimized EMC performance for automotive PCB layouts.

Pin/Terminal	Circuit Role	Design Meaning
1, 7	VIN	Main input supply connection; accepts −15 V to +48 V DC with 60 V transient immunity.
2, 8	MON	Monitor input for early-warning comparator; connect to resistor divider to set custom FLAG threshold.
3–6, 11–12, 14–15	NC	No-connect pins; must remain unconnected per datasheet to avoid parametric shift or EMI coupling.
9	RADJ	Reset adjust input; ground for default 9.2–9.4 V threshold, or use external divider to lower trip point.
10	DELAY	Capacitor connection for programmable RESET delay timing; charges at 2.5 µA typical.
13	GND	Power ground; all GND pins must be tied to low-impedance system ground plane for stability and noise immunity.
16	RESET	Open-collector active-low reset output; sinks ≥1.0 mA, valid down to V_OUT = 1.0 V.
1	FLAG	Open-collector early-warning output; asserts low when MON voltage crosses 1.20 V ±0.05 V.

Key Features

Feature	Design Value
AEC-Q100 Qualified	Grade 1 (−40 °C to +125 °C ambient) with PPAP capability - certified for safety-critical automotive applications.
Dual-Voltage Monitoring	Independent RESET and FLAG comparators enable staged shutdown: FLAG warns first, then RESET forces hard reset.
Exposed Thermal Pad	SOIC-16 E-Pad reduces R_JA to 56 °C/W - supports 150 mA continuous output without heatsink in 70 °C ambient.
Reverse-Battery Protection	Withstands −15 V applied to VIN - eliminates need for external series diode in battery-connected circuits.
Load-Dump Immunity	Survives +60 V transients per ISO 7637-2 Pulse 5a - suitable for 12 V/24 V vehicle electrical systems.

Equivalent & Alternatives

The following parts are listed as comparable options for similar LDO regulator applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
NCV8502D100R2G	Same core regulator but in SO-8 (Case 751) package; R_JA = 165 °C/W vs. 56 °C/W; no exposed pad.	Suitable only for low-power, low-ambient-temperature applications (<50 °C) due to higher thermal resistance.	Select when board space is constrained and thermal load is <50 mW; avoid for under-hood or high-current use.
TLV73310PDBVR	10 V, 300 mA LDO with 65 µA I_Q, but lacks RESET/FLAG/DELAY functions and automotive qualification.	Requires external reset supervisor IC and protection circuitry to match NCV8502PDW100R2G's integrated features.	Choose only for non-automotive, cost-sensitive designs where supervision is handled elsewhere.

Compared with NCV8502D100R2G, the NCV8502PDW100R2G delivers 3× better thermal performance and automotive ruggedization; versus TLV73310PDBVR, it integrates critical safety functions but trades off higher quiescent current for guaranteed reset behavior across temperature and voltage extremes.

FAQ

What is the maximum input voltage the NCV8502PDW100R2G can withstand during load dump events?

The NCV8502PDW100R2G is rated for +60 V peak transient voltage during load dump events per ISO 7637-2 Pulse 5a, with guaranteed operation at VIN = 45 V DC. This rating applies with proper input capacitance (≥10 µF) and layout per onsemi application notes. The device remains functional and undamaged under these conditions without requiring external TVS clamping.

Does the NCV8502PDW100R2G require an external capacitor on the DELAY pin, and what value is recommended?

Yes, the NCV8502PDW100R2G requires an external capacitor on the DELAY pin to set the reset delay time. A 33 nF capacitor yields ~23.8 ms delay using the typical charge current of 2.5 µA and switching threshold of 1.8 V. Capacitor tolerance and temperature coefficient should be considered; X7R ceramic is recommended for stability across −40 °C to +125 °C.

Can the FLAG output of the NCV8502PDW100R2G drive a microcontroller GPIO directly?

Yes, the FLAG output of the NCV8502PDW100R2G is an open-collector NPN transistor capable of sinking ≥1.0 mA at 0.4 V saturation. It can directly interface with 3.3 V or 5 V microcontroller GPIOs configured as pull-up inputs. No level-shifting is needed, and the 1.20 V internal reference ensures reliable detection across temperature and supply variations.

Is the NCV8502PDW100R2G pin-compatible with other devices in the NCV8502 family?

No, the NCV8502PDW100R2G uses the SOW-16 exposed-pad package (Case 751AG), while SO-8 variants (e.g., NCV8502D100R2G) have different pin counts and assignments. Pin mapping differs significantly - for example, RADJ and DELAY appear only on SOW-16, and GND is distributed across multiple pins. PCB redesign is required for substitution.

What is the minimum output voltage at which the RESET function remains active for the NCV8502PDW100R2G?

The RESET function of the NCV8502PDW100R2G remains fully operational down to V_OUT = 1.0 V, as confirmed in the datasheet's "Reset Function" section. This ensures reliable reset assertion even during severe brownout conditions where the output has dropped >90% from nominal, enabling fail-safe shutdown before logic corruption occurs.
